Professional sports teams take note! Retire your destructive CO2 cannons and use this design for shirt-to-fan delivery. This giant slingshot built from common hardware sends t-shirts flying.

I am a home schooler in Half Moon Bay, California. My Dad and I build things together. I've been riding horses for about 6 years. We have 2 pet chickens that provide us a lot of interesting entertainment. I also paint architectural and equestrian watercolors. Golf is one of my new hobbies. I'm studying for my hunting license and amateur radio operators license this year.
