This little intriguing gadget will fascinate your guests (but maybe not as much as with Homer!)

Scientific principle: this bird demonstrates heat transfer and the laws of thermodynamics, thanks to two linked bulbs that contain a liquid in a vacuum (so it is wrong to think that it is a perpetual motion).

See this video for a deeper understanding! Will you understand its mystery?

Dimensions (approx): 7” high, 2×2” large)
