This instructable is on how to turn a glass of dirty water into a glass of clear water using simple household items. It doesn't commpletly clean the water but it is a fun hands on experiment for little kids.
Step 1: Materials
What you will need:
An empty 2 liter bottle
A paper bag
A table spoon measurer
Step 2: Making It
Cut off the top of the bottle.
Place the top of the bottle upside down inside of the other half of the bottle.
Tape the top of the bottle down.
Cut the bottom of the paper bag off and put it inside of the bottle.
Step 3: How to Use It
Poke a teeny tiny hole in the paper bag.
Pour 2 tablespoons of salt into the bag.
Pour a glass of water mixed with dirt into the bag.
The water should start to drip into the bottle way cleaner than it was when you poured it in.
Step 4: Your Done!
Every time you use it you have to use new paper bags and salt. The water will be a lot cleaner, but not clean enough to drink. This is a really fun hands on experiment that little kids will enjoy.
