Bobbleheads are awesome but they only bobble for a little while when you doink their heads. The solution is to hire a manservant to continually bonk your bobblehead collection so there is constant bobbling. Or you could get one of these DIY Solar Powered Bobbleheads. Each bobblehead is a papercraft figure that you easily put together yourself. Inside each one is a solar powered rocker that keeps your bobblehead bobbling:
Because they’re super lightweight, ambient indoor light from a room should be enough to keep them rocking continuously. Which means your butler can go back to making you drinks and shining up your batmobile instead of bobbling your bobbleheads. Each one sits on it’s own little pedestal and they come in your choice of skeleton, ninja, tiger face and vampire. It takes about 20 minutes to assemble each- no tools required. $15.95 each from Vat19.
