This woman LOVES ‘The Rainbow Sponge’ [VIDEO]

My grandmother, of all people, sent me a link to this video!

And, I'll admit, I'd never heard of the Rainbow Sponge before. Was it like Rainbow Brite crossed with Squarepants?!?

But, from watching the video, I guess it's the best invention since Happy Hotdog Man!

She's so over the top, it almost makes me want to buy one just to see what kind of designs, tiles, and squiggles I can make!

 Listen to her squeal over painting!
