Hamza makes a special entrance to introduce one of his personal favourite shapes: the cube. A cube is sort of like a square but has a bigger personality...just like Hamza! In this episode, we'll meet cubist Pablo Picasso, find out why ice cubes make an awful necklace, and face the legendary Hound of Doom in a quest to make giant cubes.

4 segments include: INVESTIGATION/HANDS-ON: Han Ru and Stefano go on a cube hunt and meet 15-year-old Antoine Cantin, who holds the world record for speed-solving the Rubik’s Cube. He shows them how to hone their cube skills by making cube nets. CHALLENGE: Two teams race to build a huge cube that’s equal on all sides. Not so easy when they must travel through the lair of the Legendary Hound of Doom (actually a cute puppy) to gather the blocks they need for their gigantic “cube of cubes.” BRAIN BENDER: Trevor and Jason must stack six cubes so that each cube touches all of the others. It may sound easy, but you’ll really need to bend your brain to figure this one out. EDUCATIONAL TAKE AWAY: Cubes are three-dimensional shapes made up of 6 squares or faces, 12 edges and 8 vertices. They're also called three dimensional platonic solids, 6-faced polyhedrons, or hexahedrons û if you want to get fancy. They can be made using 11 different cube net patterns.
