Step 1: What You Need
all you need are some friends, and a lot of pre-blone balloons.

I got people who have a lot of energy and aren't afraid to get in trouble.
Step 3: Get It Done
find 2 hiding spot for a lookouts one to see if there coming and one to tell you if they are coming. then get way to get the balloons from one place to another. I used my mom to get them to my class room. dump all the balloons in your targets work airy. and run.
