I remember getting this stuff for my birthday!!! I was in first grade, so it must have been '76. Or maybe it was 96, whatever. I thought it was the coolest thing. That is until I put the wet sand back in the bottle. It didn't pour very well after that.
but what it DID do was clog up the bathroom sink better than anything else I had tried, previously!!!! It was awesome, and it made a huge mess, and I probably got the shit beaten out of me, but have conveniently blocked out all memory. Ahhh........to be a kid again.
Well I'm still a kid, but people gave me better presents back then.
