Playing with X-rays


Google has another clever doodle today (it's hard not to post EVERY time they have a special doodle), to celebrate the 115th anniversary of the discovery of x-rays, and GeekDad has an easy way you can "play" with x-rays with your kids:

 "While it’s not so simple to do x-ray activities with your kids at home or in the classroom, there is a related activity tied to an interesting discovery made in 2008: you can actually generate x-rays by simply ripping a piece of clear adhesive tape off a roll. That’s it. Just regular household tape. Of course, you do have to do it in a vacuum. But even if you don’t have a vacuum chamber handy, you can observe a similar effect by taking an ordinary roll of tape (clear or duct tape works well) and ripping it off the roll in a totally blackened room. Give your eyes time to adjust, and you’ll see a flash of blue light — the same kind of emission, except given off in the visible spectrum." via GeekDad

Is there anything duct tape CAN'T do?

Bonus: If you click through the logo's link, it takes you to the search page for X-rays, and the very first image in the smple of image searches is this:
