Lava Lamp

We're bringin' Disco back with this swell homage to the 70's classic.

You will need:
  • Plastic bottle, any size
  • Vegetable oil
  • Water
  • Food coloring
  • Pie pan (for spills)
  • Antacid, such as Alka-Seltzer (one tablet, cut into quarters.)

How to:
  1. Place bottle on pie pan.
  2. Fill the bottle halfway with oil. Add water to an inch from the top.
  3. Add 10 drops of food coloring.
  4. Drop one quarter of antacid into bottle and cap.

The antacid forms lava bubbles.


Not nearly as Brady-tastic as I was hoping. The lava "action" was cool for about a minute or so and then it all sort of mixed together. I'm not sure if we put too much coloring in (we may have gone over the ten drops), shook it up too much or what. The bubbling from the antacid ended so quickly that we just dropped the rest of the tablet in and that may have cause everything to combine too quickly. Who knows.

Yeah, we did a lot of shaking, but I thought oil and water didn't mix.

Got five minutes and want to keep your kid entertained while you make dinner?  This could be the craptastic craft for you.
