How to Make a Foam Machine

In order to add flair to a party, you can add a foam machine. Believe it or not, you can make your own foam machine pretty easily. Start with step one, below.


  1. 1
    Put a trashcan upright inside a inflatable pool. Place it wherever you'd like. If you want to move the pool and the trashcan, you can do it later.
  2. 2
    Run a garden hose from a hot water source into the trash can. Let it shut over the rim of the can and simply hang inwards, not touching the base.
  3. 3
    Do the same with a vacuum hose. Try to place it inside the can directly next to the garden hose. If you have heavy-duty tape, you can tape the hoses together.
  4. 4
    Let the hoses firmly run into the trashcan. Turn on the hot water, then fix the vacuum to "blow" or "reverse". You will need to alter the flow of water so that it balances the intensity of the air which is coming out of the vacuum hose.
    • If it is done well the water will be blown around the inside of the trashcan and around the sides of it as soon as it exits the hose.
  5. 5
    Put a large amount of soap into the trashcan. Squeeze large amounts of soap into the center of the trashcan, where the force of the vacuum is whooshing the water around swiftly. This will instantly generate huge amounts of foam that will spread out of the trashcan. Eventually it will start to fill the whole room. If the foam discontinues rising, merely add more soap and repeat whenever the foam discontinues to rise.
    • The foam will be thick enough to cover the room with your hands or spades if it doesn't instantly reach all the areas. Sometimes the inflatable pool may fill up slightly with water that didn't make it out into the foam. If this happens you can choose to assist the pool with a bowl or bucket, but huge amounts of water typically shouldn't build up if the trashcan is large enough.


  • Be careful in choosing your soap because some soaps may trigger allergies.
