You might be looking at the title and thinking, “This doesn’t sound safe!” In fact, when my son saw me type this title, he said, “But Mom, that would be dangerous! Please don’t do it!” But the fireworks that we’re looking at aren’t the kind that you have to do outside with close adult supervision- these are fireworks that you can do even with a preschooler!

This simple experiment is packed with science concepts- density (the oil floats on the water), polar and nonpolar substances (the oil and water don’t mix), and even reaction rates (if you try it with cold and warm water)- but it’s easy enough for kids of any age to watch or do.
