And if your science inquiry doesn't go as expected, you can expect our customer service team to help. Fill the bottle up about 1/4th (1 quarter) with water. DIY Lava Lamps are a classic, science activity perfect for all aged kids. Understand the working principle of a lava lamp clearly by performing the lava lamp experiment given here. Your kids will love exploring colored water and oil, but a surprise ingredient will make this science activity even more exciting! Now the interesting part is when the bubbles disappear on the top, and the colour falls back. An oldie but a goody, this lava lamp experiment uses several techniques for making the lamps, and teaches kids about liqui Since ice is less dense than water, it floats. Real lava lamps use a polar and non-polar liquid just like our homemade one did. At the top, the gas bubbles pop and escape into the air, allowing the dense water to sink back to the bottom again. Next, use a pipet to add an inch of colored water on top of the dish soap. The food coloring is water-based, so it will also sink and color the water that is now at the bottom of the flask. Use simple household items such as vegetable oil, food coloring, Alka-Seltzer and a bottle to create chemical reactions and funky balls of color that move around like a real lava lamp. Watch as the color sinks through the oil. Instead, a layer of ice forms on the surface, leaving liquid water underneath. What if you drop a whole tablet in? Fill the bottle up about 1/4th (1 quarter) with water. Now, wait for a few minutes until the water and oil get separate. With the apple cider vinegar it was a little like a gold colored lava lamp. It's always a hit with the kids. To figure out where your new liquid would fit in the column, you can measure the density of all the liquids. Oil molecules, however, are non-polar they don't have a positive or negative charge, so they are not attracted to the water molecules at all. Be prepared for a little mess, but this homemade lava lamp is so much fun! The oil floats on top of the water because it is less dense or lighter than water. Bottom line?

Liquids of different densities: honey, corn syrup, dish soap, water, vegetable oil, rubbing alcohol. Use the funnel to fill the water so that water doesnt spill outside. For example, salt water is more dense than regular water (which is why it's easier to float in salt water than in fresh water!).
