Hamza is determined to find out why so many instruments - like flutes, horns, and organs - are cylinders. What's so musical about that shape? To find out, we'll make instruments out of recycled junk, play music with water glasses, and meet "Bubba" Bach, the inventor of flatulent-sounding novelty horns.

4 segments include: INVESTIGATION/HANDS-ON: Han Ru and Stefano go on a hunt for cylindrical musical instruments. Later they meet math and science student Phoenix, who challenges them to create musical cylinders out of water glasses and match the notes on a xylophone. The Investigators learn that the length of a cylinder determines whether it makes a high or low sound. CHALLENGE: Hamza gives two teams of kids an assortment of cylinders and challenges them to make musical instruments they can play. Our panel of Look Kool kid judges will score the two orchestras on their unique instruments and quality of music. It’s a musical cylinder Jam! BRAIN BENDER: Malinka and Annabelle are presented with a six-glass line up: the first three glasses are empty and the second three are full of water. Their task is to make the glasses alternate - full/empty/full/empty/full/empty - using just one move. Can you guess the surprising trick in this brain bender, before they do? (Hint: The “move” is to pour the water from one glass into another). EDUCATIONAL TAKE AWAY: Many musical instruments are made out of cylinders - both instruments you blow air through (horns and flutes) and instruments you hit (drums and chimes). It’s easy to regulate the sound a cylinder makes - the longer the cylinder, the lower the sound.
