So we had a play date the other day and the girls were doing science experiments. With Halloween  not too far away we decided to do the "ghost balloon" which teaches the kids about gases.

What you'll need:
water bottle (or glass bottle)
Balloon
4 TABLESPOON Vinegar
2 TABLESPOONS Baking soda
funnel or piece of paper.


Directions:
put 4 tablespoons vinegar into the bottle.  Open the balloon as wide as you can and using either a funnel or make shift one fill the balloon with baking soda. Cover the lid of the water bottle with the balloon being careful not to spill the baking soda in..yet.

When you're ready  dump the contents of the balloon into the water bottle  and watch as the baking soda mixes with the  vinegar and chemically reacts by making a gas that it then trapped into the balloon giving the illusion that the balloon was blowing itself as if a ghost was doing it ;)

The girls favorite part was when the balloon started to fill with  the gas I picked it up and started saying, "oh please don't pop on me...please don't pop!" it did not- but it ended up in teh sink just to be safe!

There isn't much to this pin. It was meant for a wedding announcement, but I thought it would be a nice pin for a rainy day (although it's not raining at the moment). You just need two cups and some yarn. Poke a hole at the top and string the yarn through- tie a knot.  Do the same to the other cup. Now have one person stand in one spot and have the second person walk until the string is straight. Now one person talks and the other person will hear you, just like a real telephone! It's a lot of fun and the girls are in full amazement right now :)
