Singing Magnets: Wonders of Science

Here's an unique toy to play with or gift to a science lover.

Called the  "Singing Magnets", this pair of two magnets when tossed into air come together  and make a singing sound as they vibrate off each other; no battery required! The higher you toss them the longer you hear the sound. Just be sure to not drop them.

Available for US$ 7.95 from here
