· Water bottle of about 12.7 ounces

· A ¾ cup of water using a measuring cup

· 32 ounces of Vegetable Oil

· Food coloring, any kind will work, one package of four little bottles

· Alka-Seltzer, any kind will work, just one plain pack

· Glitter, any type of glitter will work, go by preference, enough for a small dash

Step 1: To Begin,

Gather all materials, the water bottle, food coloring, Alka-Seltzer, vegetable oil, measuring cup, and glitter on a flat and stable surface.

Step 2: Add Water

Add ¾ of water into a 3/4 measuring cup.

Step 3: Add Food Coloring

Choose your favorite food coloring and put about 3-5 drops of food coloring in the measuring cup of water.

Step 4: Add Glitter

Grab a pinch of glitter using using your thumb and pointer finger and add it into the measuring cup. Repeat this step if you want more glitter.

Step 5: Add Vegetable Oil

Grab the empty water bottle and the vegetable oil (make sure to put the water bottle caps to the side for later). Fill up about ¾ of the water bottle with oil. Remember to leave enough room for the added water and for extra air.

Step 6: Mix the Two Liquids

Grab the the measuring cup filled containing the mixture of water and food coloring and carefully pour it into the water bottle, combining it with the vegetable oil.

Step 7: Break Up Alka-Seltzer

Pick up one tab of Alka-Seltzer out of the box. Break up the tablet into about four smaller pieces.

Step 8: Add in Alka-Seltzer

Slowly add the broken up Alka-Seltzer into the bottle, piece by piece. Be sure to wait about two seconds in between each drop of Alka-Seltzer.

Warning: more than one full tablet can cause the lava lamp to become cloudy or to overflow.

Step 9: Observe

Watch as the lava lamp lightly bubbles up and then wait about a minute or two for the combination of materials to settle down.

Step 10: & Now, You Are Almost Finished!

Screw the bottle cap onto the top of the bottle and place the decorative lava lamp wherever you wish.

Step 11: Extra Note

Once the bottle cap is back on and the lava lamp has settled, you can go back and add more pieces of Alka-Seltzer to it in order to make it bubble up some more. However, the lamp will overflow more quickly once everything has settled so make sure to wait about ten seconds in between extra pieces of Alka-Seltzer.
