Raining Fire Turning Up The Heat They may look harmless, but what will happen to this collection of 2000 Ping-Pong balls when Tim Shaw turns up the heat? Flaming Balls Tim Shaw and the group tests just how flammable 2000 Ping-Pongs balls can be, with surprising results! Up In Flames 2000 ping-pong balls go up in flames! This huge fireball is a result of torching the highly flammable, celluloid balls. The Power of Air All that is holding these two sections of rope together, is the power of air! Tim Shaw asks these volunteers to test the suction power of a vacuum with these Magdeburg Hemispheres. Safety Check Tim Shaw double checks the experiment before he turns up the heat on these Ping-Pong balls! DIY Motor How many pieces would you need to construct a fully working, electro magnetic motor? 10? 8? Tim Shaw shows us you need only four. Pounds of Force The guys use a device that measures how many pounds of force is required to separate the Hemispheres. Test of Strength Pull!
