The Physics Boat Project

The latest project in Physics class was the Rubberband-powered boat. Originally thought by many members of the class to be a substandard project, it turned out to be one of the more challenging and entertaining projects of the year. The objective was to build a model boat powered only by rubber bands (no rockets, gasoline, napalm, nuclear, steam, or geothermal energy.) In addition:

  • No boat could be longer than 30 cm.
  • No boat could be deeper than about 15 cm (the depth of the rain gutter the boats were racing in).
  • No boat could be wider than about 8 cm (the width of the gutter).
  • ABSOLUTELY no explosives. We pressed this point, but to no avail.
  • To be considered successful, a boat would have to travel at least 1 meter.
  • A boat would have to start under its own power. For example, one could not fling a boat down the gutter with a rubber band and win the race. (S.O.)

    Over three days, our boats were tested in two side by side 2.72 m rain gutters. Competitors were drawn randomly out of a container and raced. Then there was a tournament-style competition for the first two days. On the third day, re-engineered boats could be retested. When the dust settled, an Avian boat built by Amanda Knowlton and Tennile Sturk came out on top on the third day. The Avian boat, both fast and capable of extending that speed over the length of the gutter and more, won the day. Of course, for the first two days, The Lego POS, built by Andrew Beckett and Ben Dyer, was on top. It wasn't incredibly fast, but it could go the distance.

    Obviously, speed is a factor in deciding which boat would win the race, but most important was toatal work exerted (force over a distance).

    Overall, boats with a propellor driven engine won out over paddle-wheel designs.

    After the vacation, I will try to get the results of testing and display them here.

    This is Amanda and Tennille's boat. Eventually, it came out on top. Awesome boat.


    The Hershey's Milk Chocolate container on Josh P's boat was a nice touch, but that was its best feature. It never left the starting line.

    Here is a picture of Matt and Piper's spoon wheel boat and Glenn Davis RP's 2 Pump leaving the starting line.

    Steve Olson's boat, the Aries, is shown here actually winning a race! Apparantly, the unlucky name of the boat did not affect its performance.

    Here is that little scrapper, the Lego POS. In first place for two days, it was dethroned by Amanda's and Tennille's boat.

    More pictures will be up soon.
