DIY Lava Lamp - lamp appearing green with bubbles inside bottle I was amazed about how lava lamps are made. I tried making one at home. Alka Seltzer is what makes the fizzing and floating effect, but I don't have it, so I tried an experiment using the chewable aspirin. It doesn't really fizz the way Alka Seltzer does, but still it's beautiful.

Supplies:

empty bottle
vegetable oil
food color
water
battery operated candle light/lamp
aspirin or any fizzing tablet (substitute for Alka Seltzer)
funnel
Note: if you don't have fizzing tablets salt or baking soda will work as well.

Steps:

Pour water filling 1/4 of the bottle. Use a funnel to avoid spilling.

Add cooking oil. Leave a little space so it does not overflow when tablet is added.

Add a few drops of your desired food coloring.

In my case I put 10 tiny aspirin tablets. But if you use Alka Seltzer 1 tablet will be fine.

If you're not satisfied with the fizzing effect of aspirin add baking soda or salt.
Place the battery operated light behind the bottle or find a glow stick and place it inside the bottle.

Display it in your room. You can turn off the lights as it can be used as dimlight.
