A foam party comes down to two numbers: how many people and how long. From those we size the cannon's output and the amount of foam. We bring the rest.
Which package you need, by headcount
Output is matched to the audience. A group of five-year-olds does not get the same foam as a village street party of three hundred: it reaches their chests and frightens them.
- Up to 100 people, birthdays and end-of-year parties: one cannon with the output turned down for younger guests. Two hours, from €350.
- 100 to 300, street parties and town festivities: one high-output cannon, with the two hours extendable. From €550.
- Over 300, festivals and fairs: several cannons and a duration built around the programme. The price depends on the venue, so we work it out case by case.
What we ask before confirming a date
Three things, and none of them is the budget:
- Where the cannon can stand, and how far that leaves it from the crowd.
- What surface is underneath. Foam is slippery, and the packed earth of a village square is not the polished floor of a sports hall.
- Where the water drains once the session is over.
If the party is on a public street, the town hall will ask you for public liability insurance and, depending on the municipality, an occupancy permit. We have set it out in our guide to insurance and permits for municipal events. This is how we work with town halls right through the festival season.

The foam, and who is watching it
The foam is biodegradable and non-toxic. During the session the technician stays with the cannon, controlling how much comes out and where it points. That is the difference between a dance floor people enjoy and one where nobody can see the ground.
If you are after more ideas for an end-of-year party or a summer camp, they are collected in our article on themed parties. And to carry the night on, foam pairs with the neon party or the mobile disco.
