Today is the first day of the Science Saturday blog hop, organized by Sarah @Little Bins for Little Hands. Each week a group of bloggers will feature fun science experiments that you can try with your kids. We love doing science experiments at our house! Anything can be science and everything is new to kids, so it's easy to wow them, even with simple things!
We've never done any baking soda and vinegar activities, even though there are so many good ones out there. But these Exploding Paint Bags from Growing A Jeweled Rose looked like so much fun we had to give them a try. I practiced a little before Kay was around, to make sure I got the idea right. I found that 1/2 cup of vinegar and 1 tbsp. of baking soda seemed to be a good combo for making the bags explode. I also grated up some chalk to throw in there for some color.
Kay helped fill up the bags. The first few times we put the baking soda in a tissue and folded it up to drop in the bag, but soon we skipped the tissue part and just dumped the baking soda in and sealed the baggie up quick. Then she'd toss the bag and a few seconds later...POP!
She loved watching it fizz for moments after the pop. She asked, "Is it hot?" and wanted to touch it and step in it. I made a big deal about calling it lava, while making a mental note to actually use it as lava at some point. She mixed the chalk colors to a lovely shade of mud brown, but even when the chalk ran out, we still did a few more bags; she didn't care about the colors.
Consider this the first of many future baking soda and vinegar adventures!
