Here is an example of a pull top water bottle.

I wanted parents to know that students may bring water bottles to school for use in our classroom.  Our drinking fountains are in the hallway and children lose valuable class time when they need to leave the classroom to get a drink of water.  An easy solution to this is to allow water bottles in the classroom.  Water bottles need to have a pull top and be filled with water only.  Pull top bottles are less likely to spill. You may still pack juice in your child's lunch, but it's water only in the classroom. Please make sure to write your child's name on their bottle.
