The Balancing Button Pendulum
Steps:
- Tape one end of the string to the top of a doorway.
- Use the hole puncher to make two holes in the paper cup.
- Tie the other end of the string through the holes to hang the cup.
- Place five buttons inside the cup to give it a little weight.
- Set up three cardboard strips as pins on the floor nearby.
- Pull the cup back and release it to knock the pins down.
- Try to keep the buttons inside the cup during the swing!
Safety Tip:
Ensure the doorway is clear of traffic and the string is not left unattended to prevent tripping.
