Phil builds a balloon powered car in the lab. Then he tries to make one big enough to ride. Plus, Newton's Cradle out of bowling balls, how Guinea Pigs got their name and Newton's 3rd Law.

Phil starts with a Popsicle stick catapult, then he uses everything he knows about elastic energy to build a full-size catapult that hurls pumpkins! Plus, a maxed out paddle wheel boat and a historical re-enactment (sort of).

Phil starts with a balloon powered hover disc, then tries to make a maxed out version big enough to ride. In fact, why not make 2 & then race them! Phil also tries to use the power of friction to climb the walls & even to fly

Ever wanted to build a bridge out of pasta? It's not too hard & works better than you'd think. But what if we were to try to make a pasta bridge big enough for Phil to walk across?

Magnets have poles - when you put opposite ones together, they attract. But when you but the same ones together, they repel. Could we find magnets powerful enough to repel each other and float Phil off the ground?

What makes boats float? Tinfoil doesn't float, but a boat made of tinfoil does. It's all about how you build it. Watch as Phil builds his human-sized tinfoil boat several times before he figures it out.

The old 'vinegar and baking soda volcano' needs an overhaul. What happens if we use 60 times as much? What about using 100% acid? What about even more reactive chemicals?

Learn how to use air pressure to make your own, home-made rocket out of a plastic water bottle. Phil maxes this out by over-pressurising stronger bottles and finally by building a giant rocket out of plastic bottles.

Phil gives himself super strength using the power of simple machines to move, lift and roll a machine he could barely budge otherwise. Plus, lift yourself with one finger and watch cavemen discover the wheel.

Solid, Liquid, Gas and all things in-between. Phil fills a giant trough with corn starch mud to see if it's solid enough to run across. Plus, makes a giant sledgehammer out of a frozen pumpkin and giant rock candy.

Start by learning how to fold the paper airplane that won the long distance record. Phil finds out making a giant paper airplane that will still fly is way harder than you'd think. Plus, terminal velocity & indoor tornadoes!

How can you balance a potato on a stick and can Phil balance on a tightrope using the same science? What's better for balance, staying put or using something that spins? Phil designs a gyroscopic stabilization backpack.
