Experiment with Rubber Bands and Cans

The video tutorial introduces a challenge to make a can return when called, similar to a pet. It provides a list of materials needed and detailed instructions to perform the experiment. The tutorial explains the science behind the experiment, focusing on energy storage and release using a rubber band mechanism. The can moves due to the energy stored in the twisted rubber band, which is released as it unwinds, propelling the can back.

What is the main challenge presented in the video?

• To make a balloon pop

• To create a flying machine

• To build a robot

• To make a can come to you when called

• Tie a knot in the middle

• Stretch it as far as possible

• Cut it into pieces

What should you be careful with when making holes in the plastic lids?

• The weights

• The rubber band

• The scissors

• The tape

What is used to secure the rubber band inside the can?

• Tape

• Glue

• Nails

• Small sticks

What is the purpose of the small sticks in the experiment?

• To make the can spin

• To weigh down the can

• To secure the rubber band

• To decorate the can

What happens to the rubber band when the can is moved away from you?

• It breaks

• It changes color

• It stretches and stores energy

• It melts

What does the rubber band do when it releases its stored energy?

• It makes the can move back towards you
