Ok, how many times have you heard, "Teacher, my paper got wet!" Well, it got wet because you keep setting your sweaty water bottle on your table! LOL! I allow my kids to bring water bottles because I don't want them asking every 15 minutes to go get a drink from the fountain.
My fantabulous teammate showed me how a 1/2 gallon milk jug would save my sanity! I have each student bring in a clean 1/2 gallon jug.
I cut the jug so that a water bottle will fit in it. I start cutting directly across from the handle. I cut about half way down and then cut around both sides. I leave the handle side alone.
