Jello 

Here is the first jello picture that we thought was successful. You can see the bullet at the bottom of the jello.

The jello explosions produced some interesting shapes. This one looks somewhat like a whale as one student put it (credited to Nidhi)

The jello is exploding to the left.

Similar to the previous picture.

Here we experimented with two Jell-O pieces at the same time.
This one was a bit more successful.
