You could ride a hover board or stream music to your levitating speaker, or you could fill your home with levitating light bulbs.
Sure, a you could buy a boring home-brand light bulb that has to be plugged in for 60c, or you could pre-order this amazing levitating source of illumination for 300-and-something-dollars on Kickstarter. Look! It's magic!
You turn it on and off just by touching the wooden base. Oh, and you can spin it around to make a cool lighting effect. And did we tell you it lasts for 22 years? Well, it does, so you can justify it as a sustainable, buy-once-buy-right kind of purchase if that floats your boat (only $14 a year!).
