All-Period Day Catapults

During All-Period B Day on January 17th 2020, Grade 9 students from Ms. D’Antonio’s math class were tasked with a challenge: to create a device that would launch a marshmallow the furthest with the given materials.

Their materials included ONLY…

  • 2 rubber bands
  • 5 straws
  • 5 popsicle sticks
  • unlimited masking and packing tape
The winner – launched 30 feet!! Design based off of a crossbow.

Another key design trait: their designs must be set in place and only triggered to launch by the tip of a pencil. (ie. students could not pull back their design like a sling shot to launch it, it must be already pulled back and set into place).

A torsion-powered catapult.
