Coil Gun

Description

We made two modifications on the coil aiming to make it more powerful. First, we bought a photoresistor, and plan to modify the circuit and add one more coil to have a two-stage acceleration. The second change is from a donut shape to a flat pie shape.

The coil gun can be really powerful — enough to send you into jail. However, we are tired of its encounter with hard objects. How would it behave if it meets a hard-yet-soft object: non-Newtonian fluid?
