Hawaiian Roll Chunkin

Hawaiian Roll Chunkin

Michaela Salciccia

The Hawaiian roll chunkin competition is a very old tradition that TMS has done for many years (Except during covid). We have had multiple past winners, and hope to have even more to come. As you play in this competition you will have to build an item of your own, such as a catapult, Ballista, or Trebuchet. If you do end up winning this competition there are multiple prizes you may earn. 


When competing in this competition you have to follow a few rules!

  • Your device can be powered by torsion, tension, centrifugal, or counterbalance.
  • Types of devices include trebuchet, ballista, and traditional catapult.
  • You must build your device. It can not be store-bought.
  • If you use a kit please let your teacher know.
  • You are encouraged to get help from your family.
  • You will be given a Hawaiian roll at launch time, no alterations allowed.
  • If your device is unsafe, you will not be allowed to launch.

This tradition of ours was inspired by a youtube channel called pumpkin chunkin. Since we wanted our competition to be safe we decided to use Hawaiian rolls instead of pumpkins. Here is the link if you want to check it out!!! Pumpkin Chunkin 

They have a few useful steps for competitors, called the A-B-D-C-E Engineering process. A stands for Ask, B stands for Brainstorm, D stands for Design, C stands for create, and finally, E stands for Evaluate and Refine. This all was talked about on a slideshow that was made for competitors. Here is the link! Hawaiian Roll Chunkin slideshow
