Answer 1

My Rube Goldberg Machine to squeeze toothpaste will involve the following steps:
1. A marble will be released from a funnel at the top of the machine, rolling down a series of ramps.
2. The marble will hit a lever at the bottom of the ramps, which will cause a small toy car to race down a track.
3. The toy car will hit a domino, causing a chain reaction of falling dominos.
4. The last domino will hit a switch, turning on a small motor.
5. The motor will spin a wheel, which will pull a string attached to a pulley system.
6. The pulley will lift a small platform, releasing a balloon filled with air.
7. The air from the balloon will push down on a lever connected to a toothpaste tube, squeezing the toothpaste out onto a toothbrush.

Materials needed for this machine include marbles, ramps, a funnel, a toy car, dominos, a switch, a small motor, a wheel, string, pulleys, a balloon, a toothpaste tube, and a toothbrush.
