- One student will be in charge of blowing up the balloon, do not tie the end.
- Two students will hold each end of the 5 meters of fishing line and stand apart far enough that the balloon may travel down the fishing line.
- One student will be responsible for timing the balloon to see how long it takes to travel across the fishing line.
- Feed the straw through the fishing line so that it may move freely.
- Place a piece of masking tape across the top of the straw and attach the balloon to the masking tape (make sure the balloon is not tied)
- Blow up the balloon.
- Hold the end of the balloon so that no air may escape until the timer says go!
- Release the balloon and measure how quickly it travels from its start position to its ending position.
- Record the data and measurements used
- Repeat five times, blowing the balloon up to different sizes each time, collect data, and compare.
