Project Milk Bottle

This is our milk.

We drink at least 2 of these a day.

So let's round up a bit and say we accummulate 16 milk bottles a week.

That's a lot of bottles and lids.

So far some bottles have been used for:

a marker/pencil/pen holder

jello cups

a fabulous rocket created by Eric (oh, and space monkey to fly in the rocket created by Scott)

and bath toys.

 no matter how many times you tell her not to drink the water...

She is filling her milk bottle with another container and she would look up every so often and cross her eyes.  She had no idea I was watching her and taking her picture :o)

What else can we use them for? 
We have 5 weeks left and that's at least 80 bottles!!
I would LOVE ideas!
