A smart drinking straw trick from Sarah, via my spiffy new hack submission form on Tumblr:
Ever have a kid who wanted to tip the cup because the straw was so long that it was above the kid's head with the cup on the table?
Bend the straw to a 90 degree angle. Then use your fingernail to put a crease in the fold, and squeeze together. The straw should retain the 90 degree bend, and slow the drink rate a little.
YES. That should prevent a few spills when you're out to eat with your kids. Thank you, Sarah!
