Tim makes a noise!

The ZUBE TUBE gives weird audio effects when you talk into one end. There are two cups inside, joined by a long spring, which vibrates when you talk into the tube.

Next, a percussion instrument that creates strange vibrating or rattling sounds.

Designed by Marion Hine and then marketed by the NAEF company in Switzerland in the early 1980s, this unusual item is called a RI-RA. It consists of a strip of leather with a number of small wooden blocks attached to it. Flexing the RI-RA causes the wooden blocks to hit each other, producing a very distinctive sound.

Tim then demonstrates a better version of the bullroarer. He showed one in a recent video that used a wooden ruler. He subsequently located a version that uses a metal ruler, which gives a better sound, and which he demonstrates here.

A wooden double flute, which allows two different notes to be played at the same time.

Finally the ‘singing rod’. It has very fine lines engraved into the metal. Tim then put some rosin powder on his hand, and now when he runs his fingers along the metal, it causes the rod to vibrate and creates a high pitched singing sound!
