Kid Concoctions: 2 Bubbling Lava Lamps

This kit is simply groovy! To make the lava lamp from the three included ingredients—glitter, oil, a fizzy tablet and water—plop the tablet in the oil and water solution and enjoy the show! The effect is very fun to watch, and although the lava flow lasts only as long as the tablet, you can get more mileage out of the lava lamp by using effervescent tablets (like Alka-Seltzer) once your supply runs out. Sneak in a teaching moment and explain why oil and water don’t mix. It’s also a great opportunity to see how effervescent tablets work! (Alex Toys, $12.68)
