Balloon Monster Science

     Chloe loves science!  Do you know the best things for toddler science?  Baking soda and vinegar of course!  We all know of the typical explosions, but did you know that they can inflate a balloon as well!?

What you need:
            2 Tbs baking soda
            1/2 cup vinegar
            Some sort of bottle a balloon can fit over
            Balloon
            Marker

     So to make this experiment Halloween related we blew up the balloon ahead of time and drew a monster face on it!  You can't really tell from the picture, but it was super spooky....  After we had our spooky face drawn on we let the balloon go to deflate it and chase it.  We couldn't find a 2 liter bottle so we used Chloe's water bottle, it worked ok.
     The first round Chloe poured everything in super slow and we ended up with a HUGE explosion mess because I couldn't get the balloon covering the hole before the reaction happened.  The next 100 times she wanted to do it we were much quicker, although with pouring so much vinegar into a tiny hole we still had a bit of a mess.  After the first two rounds we stopped measuring all together and just went at it,  It worked about the same.
     I thought it was a bit disappointing how little the balloon blew up, but Chloe thought it was AMAZING.  Know of any other cool things you can do with baking soda and vinegar?
