Brain Game - Magnetic Cannon

Build an intense desktop cannon powered entirely by magnets! Easy to assemble in minutes without any extra tools or glue, this unique device teaches kids about multiple physics concepts through the thrill of launching metal bearings to knock down a pile of wooden barrels. Just drop one of the chrome steel balls into one end and watch as a chain reaction instantly blasts another steel ball out of the other side! How does it work? As the first ball hits the first magnet it, its momentum continues through the magnet causing the next ball to accelerate towards the next magnet. The cycle happens again and again with each ball accelerating faster than the last until finally, the last ball is blasted out of the other end! Potential energy, kinetic energy, conservation of energy, momentum, conservation of momentum - There's so much kids will learn while they're having a blast with the Magnetic Cannon!
