How to Build a Party Foam Machine

What could be more fun than a bunch of slippery people running through heaping mountains of foam? Foam parties are a blast for kids or adults alike and you don't have to get an expensive machine just to throw a foam party. Find a place for your party where cleanup will be easy and build your own foam machine out of common, accessible materials.

Things You'll Need

30-gallon plastic trash can
Kid's wading pool
Shop vacuum
Water hose
Faucet adapter
20 bottles dish soap
Bucket

Instructions

- 1
  Place a clean, 30-gallon plastic trash can in the middle of an empty kid's wading pool.
- 2
  Run the hose of a shop vacuum to the inside of the trash can.
- 3
  Connect a water hose to a sink faucet using a faucet adapter. Run the water hose to the inside of the trash can.
- 4
  Position the vacuum hose and the water hose so that the ends are about halfway down the trash can.
- 5
  Set the shop vacuum to blow and turn it on.
- 6
  Turn on the warm water to the sink faucet.
- 7
  Start adding dish soap. The water will turn the soap to foam and the shop vacuum will blow the foam into the room. You can gradually add up to 20 bottles of dish soap.
- 8
  Do not let a bunch water start overflowing from the trash can, although the kid's pool will help catch runoff. Once the bubbles get going, adjust the flow of the warm water to control the water level.
- 9
  Use a bucket to empty water from the kid's pool if it starts to get too full.
