Table Top Trebuchet
You will be building a table top version of the old siege engines used in medieval
times to knock down castle walls. It will be fun to build plus you will learn
some of the physics of stored energy and motion. The trebuchet can be exhibited
at Achievement Days. Supplies for this activity will be provided (2 hours)
Build your own steamboat which actually works. Participants will need to bring
a 20 oz plastic bottle. The boat will actually move forward with the “steam”
provided by a small votive candle that is furnished. (1-1/2 hours)
Build your own hovercraft to take home. Participants will actually build a small
table top hovercraft and get the excitement of riding a large hovercraft capable of carrying an adult. Great fun. (1-1 ½ hours)
