How to Make a Mini Foam Generator

A mini foam generator is a portable device that shoots a large volume of foam into an open space. They are often used for throwing foam parties, or events where people can play in a giant pile of foam.

It can be cheap or remarkably expensive to build a foam machine, depending on the hardware you already have to hand. It is possible to find a kit for a foam machine that costs little or nothing, but it's also easy to produce your own DIY version - and it's a great way to learn about how to hack things!

How to Make a Foam Machine

To create a foam cone, you'll need a fan that can produce a good volume of air at a reasonable speed. The best option is a large industrial extractor fan, often seen on engine dynos, but cheaper alternatives include a blower vacuum or leaf blower.

The size of the tank is another factor to consider, since you'll need a large enough vessel to hold your soapy water mixture. The simplest vessel is a container, but if you're planning on having more than 30 guests at your party, then you may want to go bigger.

A foam generator is an air-operated device that sprays a mixture of water and foaming agent onto a stainless steel screen to create large volumes of foam. They are safe, easy to use, and cost less than other forms of foaming agents. They can be adjusted to the desired density of foam and are compatible with all foaming agents, both domestic and foreign.
