I had never seen the Nickelodeon Slime Cannon. There are some Fire fighter water cannon backpacks on Amazon. They have a close build to the slime blower. I thought about making one for my little one.
very cool.. i want to make a 1 to 1 scale one for me... i wasn't going to make it screen accurate.. just when i was making my other one, couple of yrs back i saw so many vacuum cleaners being thrown out, and since they were round tank like shapes, thats what i was going to use.. never got to it tho.. but maybe i will some day soon :)
