The Floating Bonsai

1 A container made of moss or lava rock houses the roots as well as a small magnet.

2 The porcelain “energy base” uses another magnet, powered by electricity, to push the tiny tree 0.8 in. (2 cm) in the air.

3 Magnetic forces then make the bonsai spin, an effect that’s both enticing and expensive. Early backers spent at least $500 to get full kits.
