Ever dreamed of keeping a butterfly in a jar forever? Now you can! Open the glass jar and activate the switch located inside the lid. Now all you need to do is just tap the lid and watch the "butterfly" fly around in a surprisingly life-like way. Powered by three AAA batteries (not included), the Science Purchase butterfly is a unique feat of micro-electronics. Everytime you tap the glass bottle you can watch it fly, flap and flutter. Gently tap the jar once for instant action! One tap willl wake your butterfly up, two taps will make it flutter and three taps will make it flap around the glass bottle. The butterfly is also activated by ambient noise and music.
