Daybreak's 'At Home Science': Making a lava lamp

Daybreak is helping you keep the kids busy, entertained, and learning during their week off from school. Thursday's experiment teaches them how to make a lava lamp!

BUFFALO, N.Y. — With the kids off from school for February break, you might be looking for ways to keep them busy in the house. Daybreak is here to help!

Every day this week, Daybreak's Melissa Holmes is trying out a different science experiment with her 5-year-old son Elliott and their friends using things you probably already have in your house. 

Monday's experiment was making a raw egg bounce. Watch it here.

Tuesday they made a chemical reaction with a balloon. See it here.

Wednesday they had fun making a marshmallow catapult. Watch it here.

Thursday, Elliott and Emmaline learn how to make a lava lamp (and learn what a lava lamp is in the first place)!


You need food coloring, cooking oil (we used corn oil), a large vase, water and Alka Seltzer.

Pour about a liter of cooking oil into the glass vase. 

Pour water into the vase and you'll see the water gathers like little beads at the bottom, because water and oil don't mix.

Then put several of food coloring (just one color) into the oil. You'll see it sinks right to the bottom.

Drop in one of the Alka Seltzer tablets. Give it a little swirl to get it going, and just like that, you have a lava lamp!

Drop in more tablets to keep it going.

The Alka Seltzer is reacting with the water stuck at the bottom of the oil. The gasses created in the reaction between the Alka Seltzer and the water create bubbles, which travel to the top, and carry some of the food coloring with it.

Friday, the week will wrap up with a treat- Ice Cream in Bag. Tune into Daybreak at 6 a.m. to see it.
