Because Friday is a long way away to wait for link love… my second in an irregular series on kid-appropriate goodies on the Internet.
Seven Incredible Marble Machines — Paul Grundbacher (Colossal)
The girls and I attracted quite a crowd with these while waiting for choir to start yesterday. Several videos at the link above, but here’s a picture of just one of them. Enjoy.

how marble-ous
Those crazy Canadians!
My son used to be a marble run fiend. He has moved on to Mine Craft but still loves videos like this. Thanks!
