DIY Lava Lamp
Lava Lamp Science Experiment - Supplies:
- Cooking oil
- Alka seltzer tablets
- Water
- Food colour of choice
- Tall clear glass
How to make a homemade bubbling lava lamp:
STEP ONE: Gather your supplies
Before we get started, make sure to gather up everything you need before hand. Have your child choose a colour of food colouring they'd like to use for the lava lamp. Make sure you use a glass that is clear so you can see through it.
STEP TWO: Prepare the water and oil
To get started, mix together a small amount of water and your desired food colour. I find it best to use a water based colour so they mix well.
Then, fill the glass 1/2 - 3/4 of the way full with oil before adding your coloured water.
STEP THREE: Observe and experiment
Now it's time to have some fun! Let your child observe what's happening with the water and oil. Invite them to make observations based on what they see, ask questions, etc. Depending on the age of your child, you may even have them make an educated guess as to what will happen next.
After observing what happens with the oil and water, break an alka selter tablet into several pieces and drop them into the glass one at a time. Watch as your DIY lava lamp starts to bubble!
When it starts to bubble up, continue to drop more alka seltzer pieces in the glass and see what happens and watch as the bubbles change!
We hope you enjoy this fun lava lamp science experiment! DIY lava lamps are so much fun for kids of all ages. The kids will be begging you to do it again soon!
