Brainstorming

Our group discussed several ideas on how to slow the tennis ball down during its fall. We wanted to be creative and effective, so we decided to abandon some of the more creative plans because we feared they would either be hard to build effectively with the given materials or would violate the rules.

Ideas Discussed

Glider

Hot air Balloon

Parachute

  • Use dowels to keep bottom open
  • Cut bag short
  • Use bag material to design original shape

Modifying the ball

  • Spread ball pieces uniformly for balance
  • Flatten ball for increased surface area

We decided to use bag material to design an original shape. In stead of using the shape of the bag we cut it to make a flat sheet of plastic from which we could cut a parachute from scratch.

Construction

Though we had ideas about how the parachute should look, we felt why reinvent the wheel, so we used a design we found online. The design we eventually used is for a model rocket recovery chute (here)
