Help! Plastic Bottles

We are going to begin creating Science Discovery bottles. 

In order to do this - we are going to need lots of clear plastic bottles with the caps on them. 

Regular water bottles are not thick enough - we need the heavier bottles - like clear gaterade or Vitamin water.  They have to be clear so we can see into the bottle! 

If you could save any of these and send them in - that would be so helpful! 

Thank you :)
