This model of a submarine is built with simply four geometric shapes components in Tinkercad.

A Square, Sphere, Paraboloid and Tube.

Print this model to enjoy, or get inspired to create Snappy Science. Stretched rubber bands are loaded with potential energy!

I have include a step by step walk through instruction on how to create this model.

Great for Students Learning about Science and How Potential Energy works!
