I take balloons filled with Chocolate sauce, strawberry syrup, shaving cream and ketchup over my head as well as 3 water balloons. They are popped by jumping up and down while wear a banned of spikes on my head.
Fill it up with air first then stick the tip of the can in the balloon and start spraying. shake the balloon so it doesn't bunch up and block the opening. I try to make a short video this week showing so you can see.
