Making Homemade Non-Toxic Glass Cleaner

A DIY science project and useful skill from Scientific American.

Materials
•    one half cup of white vinegar
•    one half cup of water
•    one half cup of rubbing alcohol
•    one tablespoon of fresh lemon juice (which will take about one lemon)
•    Spray bottle
•    Mixing bowl
•    Spoon for mixing
•    Funnel (optional)

Preparation
•    Be sure to use only measuring utensils and bowls that are not used for food preparation and eating.

Procedure
•    Pour all the liquid ingredients together in a bowl. What kind of pH levels do you think all of the ingredients have?
•    Stir this solution for two full minutes. What does it smell like?
•    Pour the solution into your spray bottle (use a funnel if you have one to cut down on spillage).
•    Clean some glass! Just be careful to not get any of the solution in your eyes.
