SpreadShot SUPER CAPACITY

It's basically the same spreadshot but has a HUGE CAPACITY. To use it, you connect the redstone on the dispensers on the bottom and the clock. You wait to 2-3 seconds and put redstone across the dispensers on the top. Now you will have a full auto cannon that fires for 3+ minutes (Probably). Also, I didn't want to test it, so BEWARE! IT IS EXPERIMENTAL. Anyway, have GREAT fun. *UPDATE* I tested it and it went GREAT! Look at the new pictures. Also, I have calculated it holds 11520 blocks of TNT. It has 2 stages. The first stage goes farther but has less of a hole, and stage 2 has less range, but has a deeper hole.
