Geek & Co. Geeker Speaker Lab

Can a glass become a boom box? Of course it can, using this cool speaker lab with its amazing sound experiments. Using a vibration speaker that activates a tray of “dancing” sand or water, kids will actually “see” audio waves. The audio jack connects to standard sockets, and there’s a fantastic 16-pg. manual. Requires 2 AAA batteries, not included. Contains chemicals- Adult supervision suggested. From Thames & Kosmos, for ages 8 yrs-teen.
