Kind of like blocks in the real world but more bouncy -- and when you scream at them they fall down. INSTRUCTIONS Regular mode: Drag and drop blocks Make noise: Clap or scream to shake all the blocks (this won't work online) HOW I MADE THIS This project uses gravity. The building blocks fall down until they are touching the hot-pink color. They fall faster and faster once you let them go. If they hit hard enough, they make a sound. MORE IDEAS I would like to change the blocks into everyday real objects of some sort....then see what else comes to my mind.
