[treacletart]

OK here's one for all your creative juices. How many kid friendly, educational, entertaining uses can you think of for an empty plastic bottle (with screw top if necesssary). I'll kick off with some easy ones: maracca, skittle, rocket ....

I know Flip! I should really be in bed catching up on uninterrupted sleep while I've got the chance but I feel like I'm on a mission now! I've been googling and Ive found some crazy sites... look at these: an underwater eye , a rain guage , drip irrigation system , and gothicmama's rocket . and a particularly nasty easter basket that looks like its crafted from snot

I see what you mean about the snot. lol
