Bringing fireworks indoors has never been easier! This fun project allows you to make your very own fireworks simply by mixing food coloring and oil and then slowly pouring the mixture into water. Create DIY fireworks in a jar as a fun afternoon project and start a conversation with children about why oil and water do not mix. Hint: oil lacks polarity. Why do the food coloring droplets mix with the water? A fun visual show for younger kids and a great science experiment for older ones, this project explodes with fun!
