This Week In Science : Painless Tattoos & Baby Science

Painless Tattoos Are Here

A team at Georgia Tech just invented PAINLESS tattoos.

The new technique use a patch with thousands of microscopic needles on one side, so small you can’t even feel them.  But the tattoo is still permanent.

The needles aren’t even metal.  They’re MADE of tattoo ink that’s encased in a material strong enough to get through your skin, then it dissolves.

Each tiny needle represents a single pixel.  And they can be arranged any way you want to create letters and designs.  So instead of a tattoo artist, you could design it on a computer, order the patch online, and stick it on all by yourself.

They also say they’ll be cheaper than a normal tattoo.  And there’s a lower risk of infection, because there’s no blood.

How To Get A Baby Back To Bed

Science may have finally figured out the exact formula for getting a baby to fall back asleep.  Walk them around for five minutes, then sit with them for five to eight minutes.  That gives you the best chance of them staying asleep when you lay them back down.
