Dry Ice is a fun and cold experiment. There’s many things you can create, so what can you make with dry ice?
Dry ice is a cool and a fun outdoor experiment. Have you ever worked with it? The big caution is that you don’t want to touch it less it burns your skin. Got that? So it has to be handled with tongs and/or insulated gloves.
With this project, you can make your own (temporary) DIY lava lamp with household materials! It’s easy and safe, and it looks very cool.
This lava lamp experiment is super cool! Your kids will love exploring colored water and oil, but a surprise ingredient will make this science activity even more exciting! It’s always a hit with the kids. So grab a few household supplies and give this lava lamp science activity a try!
