I just found out about this great kit that you can get from the folks at Pur and Safe Water Science!
The kit includes:
• PUR™ Purifier of Water packet
• stirring spoon
• 2 liquid containers
and on the site there are activity plans to go along with the kit.
No obligation – just fill in your info and they’ll send the kit to you. Just go to SaveWaterScience.org for all the details!
