This would be a likely option if you have reason to believe that filtering the water would not be enough. Make sure to check out Instructables about water filtration, it's useful!
Step 1: Supplies!
- A handful of straws (maybe 3-5) (bendy straws are best)
- A sharp implement (My Zebra F-301 was used in this project)
- Two cans of soda (And I'd like to hear about why Dr Pepper works best for this)
- A source of active heat (hot enough to boil water)
Some foil is recommended to make this project easier and more efficient, but is not vital to its operation. I will demonstrate how to use it if you have it. For this Instructable, I'll demonstrate using a campfire as my source of heat.
