Create bubbles with the sound of your voice.
Videos and Recipes
Start with this circuit: power + sound trigger + fan
Cut a hole in the bottom of the cup.
Place fan on the hole you just made. Make sure the fan blows air into the cup.
Tape the fan into place. Make sure no air is escaping from the seam.
Tape to the end of a ruler.
Connect Bits modules to other end of the ruler with rubber bands.
Use the screwdriver to adjust the sensitivity of the sound trigger to your liking.
Dip the rim of the cup in a bowl of bubble solution. (Pro Tip: Don't have bubble solution? Mix dish soap with water.)
Blow into sound trigger and watch the bubbles come out! What other sounds make the bubbles blow? Try clapping, singing or stomping.
