We took the sensory fun outside with this activity but you could do it anywhere. We've done it inside as well but it was so nice out I decided to keep the mess out there. We did this on Memorial Day so I combined beach toys with red, white and blue stars to kick off the summer. This was not a fancy set up but my kids (and my sister and I) enjoyed it so much!

Food coloring I actually like to use soap coloring. It does not stain, is food grade and safe for the skin.
Sand Toys or anything else you have that can get wet
Essential Oil to add the sense of smell
Mix baking soda with water a little at a time until you get a pasty consistency, not loose. I added glitter to my mixture, you don't have to, you could also add food coloring if you wished.
Spoon mixture into ice cube trays (you could use any trays you have, I had these in the house already) and push down to form the shapes.
I placed red and blue gems in the ice molds before I put the mixture in and my boys loved finding the surprises inside.
Place in freezer til frozen. I made ours the night before.
Toss toys, play items and tools in bin.
Pour vinegar into bowl on the side.
Have children use their tools to squirt vinegar onto the baking soda bombs. I had a bunch of little water squirters so I put some vinegar in those as well for another added fun factor. The reaction between baking soda and vinegar is fun in itself to watch all the fizzing. They really loved discovering the gems inside. When it was all melted they started running the mixture through their hands and making soups with it.
Talk to your child and the cause and effect that is taking place. If they're too young to answer questions about it, point it all out. Point out that when the vinegar touches the baking soda there is a reaction. Yes, it's obvious but each play is an opportunity to learn something. You'd be surprised what they retain even when they're very little. I did this with a 20 month old and an almost 5 year old. They both equally enjoyed this activity.
