Rent a cold spark machine

A cold spark machine creates fountains of sparks without fire or pyrotechnics. Inside the device, titanium granules are heated and ejected upwards; the sparks glow brightly and extinguish in mid-air. Because no pyrotechnic charge is burned, the effect is also called cold fireworks or indoor fireworks, and because it generates no heat, it is the only viable option for indoor events. We offer two cold spark machines for rent: the lightmaXX VECTOR Spark UP with a fountain up to 5 m and DMX connection, and the Uking cold spark machine up to 5.5 m, which the manufacturer states leaves no smoke or odor. Both come with a wireless remote, granules, and a power cable. Whether you are looking for a cold spark machine, a spark machine, or an indoor fountain, they all refer to the same type of equipment.

The most common use is the first dance at a wedding: two fountains on the left and right, triggered the moment the music starts. At galas, company anniversaries, and in clubs, the same spark machine provides the show's highlight. If you want to replace the fountain with something shorter, use confetti; if you want a cold cloud for the drop, use CO2.

Unlike outdoor fireworks, cold spark machines generate no heat. The technology behind it is simple: heated titanium granules instead of burning chemicals. This is exactly what makes the indoor fountain the only option for weddings, galas, and theaters that can be used indoors without a permit. The VECTOR Spark UP can also be integrated into a light show via DMX.

Rental prices are gross and listed online—no inquiries or negotiations needed. A cold spark machine costs €149 per day to rent; three days cost €193.70. From the second day of rental, each additional day adds 15% of the base price, meaning the daily rate decreases the longer you rent. There is no security deposit, and all-risk insurance is included in the price. Confetti and CO2 are individual items at each location; you can see their daily rates on the catalog tiles.

When picking up your equipment, you have a choice: free pickup at the location with a briefing on how to use it, or delivery with setup and, if desired, support from a service technician for €59 per hour. The return process is the same. We do not ship equipment; the technology is handed over in person at 28 locations across Germany and Austria, each with a dedicated contact person. The catalog will show you how many units are available for your date once you enter your city.

Safety requires an honest assessment. The devices operate without an open flame, but the venue still decides whether they can be used. Ceiling height, distance to curtains, and the fire alarm system should be discussed in advance, especially in theaters, historic halls, and hotels. Operation itself is straightforward: set up the device, fill with granules, and start via remote control. Consumption depends on the height setting and the number of effects triggered.

What Renty does not do: pyrotechnics. There are no aerial fireworks, no stage fountains with pyrotechnic charges, and no pyro effects that require explosives permits. If you are planning real outdoor fireworks, you need a professional pyrotechnician. If you want a spark effect indoors without permits and without risking damage to curtains or ceilings, a cold spark machine is the better choice. For indoor events, renting a cold spark machine is the equivalent of outdoor fireworks.

Accessories and related categories round things out. Fog makes light beams visible and lasts for minutes, while a spark fountain provides a highlight lasting only a few seconds. For a stage show, a combination of both is worth it; for a dance floor in a hall, one device is often enough. You can see which equipment is available for your date and location in the catalog above.

Which of the two cold spark machines is right for you?

The difference is small but crucial. The lightmaXX VECTOR Spark UP reaches up to 5 m and can be integrated into a light show via DMX, making it the choice if you are already running a lighting console. The Uking cold spark machine reaches 5.5 m and is listed in the data sheet as smoke-free and odorless, which is a major advantage in smaller halls with sensitive fire alarm systems.

Both work with titanium granules, both come with a wireless remote, granules, and a power cable, and both cost the same. Which cold spark machine is available for your date depends on the location, not the price. Enter your city in the catalog above to see availability.

Height and equipment specifications are based on manufacturer data. How long a refill lasts during continuous operation depends on the height setting and output. Your local branch can provide details for the specific unit you are renting.

Confetti cannon: timing and cleanup

Confetti is the only effect here that leaves a trace behind. The catalog features a handheld Magic FX Confetti Cannon PRO, 80 cm long, pre-filled with a nitrogen cartridge. No electricity, no compressed air, no setup. You hold it at an upward angle, trigger it, and that’s it. One shot, then it needs to be refilled.

Timing is everything. The entrance into the venue and the first dance are the two moments when everyone is watching and when the confetti should fall slowly from above rather than flying off to the side. Never point the cannon at faces or the buffet.

And then it’s all over the floor. Expect to spend half an hour sweeping, and check with the venue beforehand to see if confetti is even allowed. Some venues charge a cleaning fee, while others have a strict no-confetti policy. This is the question that is most often asked too late.

CO2 jet for the bass drop

A CO2 jet shoots a white cloud into the air that disappears instantly. The effect relies on timing with the beat drop and works best in a dark room with backlighting. The catalog features a stationary jet from Magic FX, which the manufacturer says creates clouds up to 8 meters, as well as a handheld cannon that the DJ can operate themselves.

One point that must be clarified in advance: both devices require a CO2 cylinder with a dip tube, which is not included in the rental. A standard beverage cylinder without a dip tube will not work because the device draws liquid CO2 from the bottom of the cylinder. Get the cylinder beforehand from a gas supplier in your city. Anyone who skips this step will end up on the day of the event with a device that does nothing.

Confetti and CO2 are individual items at Renty. They are a supplement to the spark fountain, not a replacement. Price and availability are listed on the respective tile in the catalog above, as both change more frequently for individual items than for equipment types that are stocked in larger quantities.

What is allowed and what is not

You do not need a pyrotechnics license for the cold spark machines in this rental range. The manufacturer classifies them as exempt from approval because they operate without pyrotechnic compounds. A real pyro effect requires a permit under explosives law; a cold spark effect does not. That answers the regulatory question, but not the practical one.

The practical side is handled by the venue. They know their fire alarm system, ceiling height, and house rules, and they have the final say. Call them before you book and mention three things: which device is being used, how high the fountain will be set, and exactly where it will be placed. The answer will determine everything else, usually resulting in a location a few meters to the left.

What these devices cannot do: they are not a substitute for outdoor fireworks. Real aerial fireworks reach thirty meters or more, while these fountains work up to 5.5 meters. If you want the sky over your garden lit up, you need a pyrotechnician, which is not something Renty offers. For indoors, it is the other way around: the cold spark machine is the only option that is even feasible.

Two more points that surprise people at almost every event. The rule is simple: smoke detectors react to particles, not just smoke. A cold spark machine releases fine metal dust into the air, and an optical detector cannot distinguish this from smoke. Therefore, the relevant detector group must be discussed in advance. With confetti, the issue isn't the effect itself, but the cleanup afterward. Both cost nothing if clarified beforehand.

Safety distance and operation

Every device comes with an instruction manual that specifies the safety distance required by the manufacturer. Stick to it rather than guessing: the value depends on the model and the set height. Keep the area above the device clear—no decorations, curtains, or low-hanging floral arrangements. The same applies to the sides for people and anything else that doesn't react well to sparks.

After use, some granules will remain at the outlet. The manual explains how to remove them, and the rental location will check this upon return anyway. Accessories like granules and the remote control are included, so you don't need to buy anything extra. Unlike CO2 equipment, there are no missing parts you would need to source yourself.
