science project help?
March 16, 2013 at 4:31 AM

I have a science project I'm doing for my DS's preschool (I know I'm in the Homeschool group, I lurk. you guys have great ideas!) it's basically seeing the reaction of vinegar in baking soda and mixing colors.

there are 17 kids. I thought to do 5 trays of Baking soda split between them. but how do I give them the colored vinegar without giving them bowls of liquid to be spilled? They are supposed to be able to drip it in like an eye dropper.

any ideas would be appreciated!

     or one of those ketchup bottles that you fill up or those small soy sauce bottles that you have to kinda shake for the liquid to come out,

    You can buy icing containers that are like clear old fashioned ketchup bottles.

    You could also set out pie pans that have just a bit of liquid and give them pipettes to suck the liquid up. You'd have to refill the pie pans as they ran out.
