Hey everybody! Tegan here from Green Kid Crafts, and we are super excited to come and show you some activities that you can do at home -- with things you have at home -- with your littles. So, we're going to be showing you today how to do some baking soda reactions with things that you have.

So what you're going to need for this fun experiment is a plate -- we just chose a regular dinner plate, you can use a paper plate if you need it -- a container of some sort -- we just started using our clear dinner cups -- white distilled vinegar, baking soda of course, colorful drops -- we're just using basic Crayola Color Bath Dropz, you can find these in the bathroom aisle at the store, a dropper of some sort -- a syringe will work as well -- and then something to give them a little stir. We're just using a popsicle stick, so that's good.

Okay, so the first step you're gonna want to do is, you're going to take your three glasses and you're gonna put a little bit of your distilled vinegar inside. So let’s put a little bit in there. Okay, perfect.

So for this, we picked out -- our container had three different little color “drops” -- we have red, blue, and yellow. So, one for each one of our cups.

So we're gonna put one in each of our cups, and as you see, they've started to fizz a little bit! That's kind of cool, as they dissolve into the vinegar. So while those are dissolving, we're going to take our baking soda, and we're going to lay out a layer on our plate.

I just kind of smooth it out here, a little bit, so that we have like an even-ish layer of things to work with. All right -- now, you take your popsicle stick, and give your color drops a little spin; make sure that vinegar is getting colored... all right.

And now comes the fun part! So you're gonna take your dropper, and then... all you do is, you suck up a little bit of the color, and drop it into the baking soda, and voila! You make a chemical reaction!

Okay, there you have it! Chemical reactions with baking soda... things that you can do all at home with things you have at home.

_(to little boy) Did you have fun? Yeah? Would you do it again? (Boy: Yes.) Awesome. Come check out our blog for this idea and hundreds of others that you can do with your kid at home with things you have at home. We hope you enjoy!
