Step 1: Building the Body
Make sure you have the rubberbands in the right place so they create the tension that holds the bullets in.
Step 2: Loading and Firing
Add 2 green pellets per gap.
Grab by the firing bar and lob the grenade. The square falls out of place apon inpact causing the firing bar to be released. It shoots firing out the green pellets in random diriections.
