Pink and blue are the colour options for the gender reveal smoke devices described here: a WP40 is one device in a single colour, while an EG25 reveal pack contains three devices in the same selected colour. The challenge is choosing the right format and keeping that colour a surprise until the moment you’re ready to reveal it.

The colour is often the detail guests most want to guess, so keeping it secret matters as much as creating a striking plume. A little planning helps conceal the device, account for the garden layout and make the reveal easy to carry out.

This guide explains how to choose a smoke format and duration, prepare an outdoor space, preserve the surprise, operate the device and tidy up afterwards. You’ll also learn what to consider when weather or your garden layout could affect the scene, so you can focus on sharing the moment.

Choosing a smoke-device format and duration

Choosing coloured smoke for gender reveal starts with matching the device to your setting, colour plan and photographs. In the UK, anyone aged 18 or over can buy gender reveal products without a licence or special permit.

1. Choose a smoke-device format

   Match the format to the reveal: a handheld smoke grenade suits one brief moment, while a pack allows several planned emissions. A Gender Reveal WP40 is one device in either pink or blue. A Gender Reveal EG25 reveal pack contains three devices of the same selected colour. Choose according to how many moments you want, not simply the number of devices.

2. Decide whether you want one reveal moment or a sequence before selecting a format. Both the WP40 and EG25 options are selected in pink or blue, and every device in an EG25 pack is the same colour. That makes the pack useful for repeating the reveal effect without mixing colours. Keep the colour choice with the organiser, and avoid exposing the packaging before the planned moment.

   When choosing coloured smoke for gender reveal, consider how the device fits your camera plan and the guest experience. One device can focus attention on a single cue; several devices allow a sequence but require more coordination. Decide who will operate the device and who will capture the moment before choosing. Follow the product instructions and make sure the location has enough space.

3. Consider smoke duration and travel distance

   Plan photographs around a brief cloud: coloured smoke from a gender reveal smoke grenade hangs in the air for about 15 seconds. Wind changes how far it travels and whether it stays concentrated near the reveal. A breeze may carry it beyond the camera frame, while still air helps the cloud retain its shape. Don’t expect it to remain in one place.

4. Plan the reveal point with the camera and wind direction in mind. If guests stand in a line, consider whether smoke could obscure faces or drift across their view. A close camera angle makes the plume prominent, while a wider frame needs more space around the group. Use the expected breeze to position people and cameras, rather than relying on a fixed travel distance.
5. Plan the event around the smoke’s short display window. Have guests ready and the photographer framed before ignition, so reactions are captured while the colour is visible. Keep the device accessible to the responsible adult but concealed from guests who don’t know the result. One device suits a single planned reveal; choose a three-device pack only if you have several moments in mind.

Garden safety and product safety distances

Use smoke devices only outdoors in a fully open location, with permission and no applicable fire restriction. At a park or public venue, get permission from the landowner or venue before planning the reveal.

1. Assess fire, health and environmental risks

   Choose an open area and consider nearby dry vegetation, garden structures and anything else that could catch alight. Don’t use a device where a fire restriction applies, and avoid enclosed or sheltered spaces. Smoke and device materials can vary by product, so check the product information and handle them cautiously. These descriptions don’t replace the need to follow product instructions or avoid breathing smoke directly.

   Before setting up, check the ground and surroundings for combustible material, including dry leaves, decorations and overhanging branches. Keep the device away from these hazards, and don’t use it if conditions make safe operation difficult. Biodegradable casing doesn’t mean every part of the device can be left behind; plan to collect the used item and any litter after the reveal.

2. Consider safety around children, pets and pregnant people

   Arrange the viewing area so children, pets and pregnant guests stay well away from the device and its smoke path. Smoke described as non-toxic should not be inhaled, and not every guest will be comfortable around it. Tell guests where to stand before lighting, and keep children from handling or approaching the device.

   Choose one responsible adult to manage the setup while other adults supervise children and pets. Give any guest who prefers to avoid smoke a clear position outside its likely drift. Don’t hold the device near anyone for photographs; frame the picture from a safe position instead. This keeps the reveal organised without asking guests to gather around the ignition point.

3. Follow product safety distances

   Read the specific device instructions and follow the stated safety distances. There isn’t one distance that applies to every smoke product, so don’t estimate based on your garden’s size or copy a distance meant for another device. Keep guests, pets and garden features outside the area required for that product.

   Mark the device position before guests arrive, then set a separate viewing and photography area beyond the distance stated in the instructions. Check that the route between the areas stays clear, and keep the device away from fences, sheds, plants and outdoor furniture. If your garden can’t accommodate the instructions and a separate audience area, choose another fully open outdoor location.

4. Check the venue and conditions before bringing out the device. At a park, get permission from the landowner or venue; at home, make sure no applicable fire restriction prevents use. If wind could carry smoke towards guests, a neighbouring garden or dry vegetation, reposition the viewing area or postpone the reveal. Keep the manufacturer’s instructions available during setup, and don’t improvise a safety distance if space is tight.

Keeping the reveal colour secret

1. Choose one trusted organiser to know the colour and manage the reveal item. Tell everyone else only what they need to do, such as where to stand or when to look. For example, ask a friend to arrange the camera without showing them the contents. Fewer people handling the device means fewer chances for a label, open box or casual comment to spoil the surprise. When planning coloured smoke for gender reveal, decide in advance who will keep the colour private.
2. Keep the package closed until the organiser is ready to prepare the reveal. Most gender reveal products ship in plain outer packaging without a spoiler on the box, but opening the package can expose the colour. Ask whoever receives the delivery to leave it sealed, and move it somewhere guests won’t see it. A cupboard or closed room works better than a table beside party decorations.
3. Separate the reveal item from other party supplies before guests arrive. Use an unmarked bag or closed container, and don’t leave coloured packaging or instructions beside pink or blue decorations. If a helper needs to move it, give a neutral direction such as “bring the reveal item outside”. Avoid messages that name the selected colour, especially in group chats guests can read.
4. Plan the reveal sequence with the person who knows the answer. Agree on a cue, such as a countdown or signal from the photographer, and keep the device out of sight until then. If several people are helping, give each person a role without sharing the colour. One can gather guests while another checks the camera, leaving the organiser to manage the concealed item. A clear hand-off helps preserve the surprise.
5. Choose an alternative based on the effect you want, then use the same secrecy plan. A latex balloon can conceal the reveal until it’s opened; confetti creates a visible burst without coloured smoke. Dry ice itself isn’t coloured, so a coloured effect uses colour bombs alongside it. For coloured smoke for gender reveal, keep the colour choice with the organiser and conceal any materials that could disclose it.
6. Review the setup from a guest’s point of view before the event begins. Look for clues such as a visible colour label, an opened wrapper or decorations that give away the answer. Keep the organiser’s instructions discreet, and bring the concealed item into the reveal area only when it’s ready. A final walk-through can catch small spoilers before guests gather and cameras start recording.

Device operation and cleanup

1. Read the device instructions before setting up the reveal. Identify its ignition method and the direction it should face. Gender reveal smoke grenades use a pull ring. The WP40 and EG25 use wire-pull ignition, so they don’t need a fuse or lighter. Don’t assume every smoke device works identically. Keep the instructions beside the setup area, and let one responsible adult operate the device.
2. Position the device as its instructions direct, with guests in the planned viewing area. Keep hands clear of the smoke outlet, and don’t hold the device close to anyone for a photograph. Before pulling a ring or wire, make sure the camera is ready and the reveal cue has been given. This avoids a rushed ignition while guests are still moving into position.
3. Expect a brief change in the smoke’s appearance after ignition. Once the wire is pulled, a gender reveal smoke grenade emits grey or white smoke immediately. The coloured smoke follows after approximately 3 seconds. Tell the photographer about this sequence beforehand, so they can capture the colour rather than the initial smoke. Don’t mistake the first pale smoke for the final reveal colour.
4. Choose a still day with little wind for a more defined smoke cloud. Wind can disperse the plume or carry it away from the camera, changing how it looks in photographs. If your plan includes dry ice, test the setup beforehand with a small amount of dry ice and a smoke bomb. Handle dry ice with gloves, use it outdoors and keep children under adult supervision.
5. Wait until the device has finished operating before approaching it. Don’t pick it up or dismantle it while it’s in use. Once the area is clear, collect the used device and any visible litter, then follow the product’s disposal instructions. Keep children and pets away during collection. A biodegradable grenade body still needs appropriate handling after use; don’t leave the casing or other event waste on the lawn.
6. Finish by checking the setup area, camera position and route guests used. Look for packaging or small pieces near plants, paving and garden furniture. Set collected waste aside for disposal according to its instructions, rather than leaving it until the next day. If dry ice was part of the reveal, follow its handling guidance during preparation and clear-up; never handle it with bare hands.

How long do gender reveal smoke bombs produce smoke, and how far does it travel?

1. Plan the reveal around a short visual window. Coloured smoke from a gender reveal smoke grenade hangs in the air for about 15 seconds. Treat that as the moment to capture, not a long-lasting backdrop. Have guests in position and the camera ready before ignition. A photographer who starts framing after the colour appears may miss the strongest part of the reveal.
2. Let the wind determine where the plume travels. There’s no fixed travel distance for every garden, because moving air carries and disperses smoke. A light breeze can shift it across the frame; stronger or changing wind can break up the cloud more quickly. Check the direction before positioning the device, guests and camera.
3. Set the camera angle to suit the expected drift. If smoke is moving towards the photographer, place the camera to one side of its path rather than directly behind it. For a family portrait, keep faces visible against the coloured cloud. A wide shot can show the plume’s shape, while a closer view can capture reactions during the brief reveal.
4. Give the photographer a clear cue before the device is operated. Agree on a countdown or signal, then ask them to begin recording before ignition. The smoke grenade emits grey or white smoke first, with coloured smoke following after approximately 3 seconds. Tell the photographer about that sequence, so they continue recording through the change rather than stopping too early.
5. Choose a still day with little wind if you want the cloud to hold its shape. Wind can carry smoke away from guests or the camera, making the colour less visible in the intended frame. If the breeze changes direction, adjust the camera and guest positions before the reveal. Don’t move the device while it’s operating; follow its instructions and keep the planned viewing area clear.
6. Keep the event sequence simple to suit the smoke’s short duration. Have the announcement, countdown and camera ready before the smoke begins, rather than trying to fit several activities into the same moment. If you plan a second reveal, prepare it separately and let the first cloud clear from the camera’s view. This helps distinguish each photograph or video clip.
7. Review the finished photographs with the wind direction in mind. If the plume looks thin or off-centre, smoke may have travelled away from the camera; this doesn’t indicate that the device lasted longer or less time. For another attempt, adjust the camera angle and guest positions before using a device. Keep every change consistent with the product instructions and your outdoor setup.

Frequently Asked Questions

What colours are available for gender reveal fireworks?

Pink and blue are the colours for the gender reveal smoke devices covered in this guide. The Gender Reveal WP40 and EG25 each use one selected colour, so the reveal centres on either pink or blue rather than a mix. Think about how the chosen colour will appear against your decorations and background; neutral colours around the reveal can help the smoke colour stand out.

What types of coloured smoke products are used for gender reveals in the UK?

Options include smoke grenades, the WP40 and EG25 devices, and dry ice paired with colour bombs. The WP40 is a single device, while the EG25 is a pack; both are selected in pink or blue. Some products described as smoke cannons use powder confetti instead, so distinguish a confetti effect from a coloured-smoke plume when choosing the look you want.

How do you use a gender reveal smoke bomb safely?

Use the device outdoors and follow its own instructions for setup and ignition. A smoke grenade uses a pull ring, while the WP40 and EG25 use wire-pull ignition. Keep the handling to a responsible adult, and don’t substitute a lighter or fuse for a wire-pull device. If the reveal includes dry ice, handle it with gloves and keep children under adult supervision.

How do smoke bombs compare with coloured smoke cannons or powder for a gender reveal?

A smoke grenade creates an airborne coloured plume, while powder confetti products create a particle-based reveal. Dry ice alone produces fog, not colour; combining it with colour bombs can add a coloured effect. Choose based on the visual result you prefer and the space available. For example, smoke suits an open-air plume, while confetti creates a distinct burst of particles.

How much do coloured smoke bombs or smoke flares cost in the UK?
