Awesome cannons that will be sure to spice up your service or outreach. These cannons are great attention getters. Shoot out T-shirts or confetti towards your audience and watch them gather around. The built in pressure gauge allows you to be reasonably accurate with the items you launch. Because these cannons use compressed air, you don’t have to worry about added expenses in CO2 refills. And because the cannon is not tethered to a compressor, you can fill them up and go! The cannons are good for one quick launch and then ready for a refill. The cannons are a high quality, safe, and tested product. As long as you don’t exceed the cannons limits, you should have an awesome ministry tool for years to come!
