My kids love experimenting! This time shine the flashlight through the lava lamp while the blobs are bubbling. Break an alka-seltzer tablet into a few small pieces, and drop them in the flask one at a time. Use the funnel to fill the water so that water doesn’t spill outside. Whenever required, drop another piece of the tablet to make a flow of bubbling in case the lava lamp stops. Instructions: Fill the bottle up about 1/4th (1 quarter) with water.

Children under 3 should not participate in any activities that involve small pieces. They're not happy until you are. STEP 2: Now go ahead and fill up the rest of the jar with water. school or private event. The food coloring is water-based, so it will also sink and color the water that is now at the bottom of the flask. Adult supervision is required for all activities I share. These stick to the water droplets. Pour the vegetable oil in the bottle until is almost full. Since ice is less dense than water, it floats. As it gets farther from the light, it cools down, becoming more dense again until it sinks; then the cycle starts all over. Using a knowledge of liquid density, you can easily "stack" several liquids on top of each other! Get ready … here come the bubbly blobs! In a real one, however, the densities of the liquids are much closer together than vegetable oil and water. There are many different factors that affect density, such as temperature. The classic way to make a homemade lava lamp is to use Alka Seltzer. © 2020 Home Science Tools   All Rights Reserved, We’d like to give you a customized experience on our website. Slowly and carefully pour an inch of the corn syrup on top of the honey. Watch Scientist Joe as he makes the Lava Lamp Experiment here! We get it. Materials: Oil, water, food coloring, & alka seltzer To figure out where your new liquid would fit in the column, you can measure the density of all the liquids. What if you drop a whole tablet in? First, it is a wonderful demonstration about density. Instead of using a light, in our homemade lava lamp we used alka-seltzer to power the lamp. Break the Alka-Seltzer tablet into smaller pieces (6 to 8). They won't let you down, no matter what they're up against. Science Fun For Everyone! The denser liquid sinks to the bottom, but the lava lamp light heats it up until it expands and becomes less dense, causing it … The density of oil is lower than the density of water, and both don’t mix well. Or, to watch the full video on even more ways to make your own scientific lava lamp, click here. If you want to explore liquid density and chemical reactions, this is the science activity to try! EASY DIY LAVA LAMP. Add 10 or more drops of food coloring to the bottle until a rich color is seen. Guess what! This can explain why oil and water don’t mix. DIY Lava Lamp Experiment. Even though the amount of liquid is the same, the denser ones will be heavier. (One exception is water - it becomes more dense with cold until the freezing point, but it freezes in a crystalline structure that makes ice less dense than liquid water.). Make your very own Lava Lamp and learn about density, chemical reaction & carbon dioxide. It might erupt out of the bottle! What happens? Pour the vegetable oil in the bottle until is almost full. Can you recall the mesmerising feel of watching a lava lamp, with its large coloured bubbles rising, sinking and morphing? Science can be messy. As it dissolves it makes gas, carbon dioxide. This is a fun experiment to show your kids how different liquids don’t always mix. Break your fizzy tablet in half and drop part of it into the bottle. Like crazy easy. Individual Write a DIY Lava Lamp Instruction Manual (15 – 20 min) Students write and illustrate an instruction manual providing a scientific explanation of the theory of operation. Adding things to a liquid will also change its density. Cary, NC 27513, Copyright © 2020 Science Fun. When the bubbling stops replace the bottle cap. Want to bring STEAM curriculum to your school? What happens if you put the cap on after dropping the fizzy tablet in? Add a few drops of your favorite food coloring.

When it stops bubbling, try sprinkling some salt into your lava lamp. As it dissolves it makes gas, carbon dioxide. In a real one, however, the densities of the liquids are much closer together than vegetable oil and water. Follow the tutorial below to make a lava lamp sensory bottle in less than five minutes. In fact, as long as the bubbles keep going, my kids will happily sit there and watch it without batting an eye! The food coloring has the same density as the water so it sink through the oil and mixes with the water. 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!). Each of the liquids you used had a different density. The action you see is actually a fun science experiment as it's caused by the density and polarity of the substances. Use food coloring to color a little bit of corn syrup (if it's the light kind; just leave it brown if it's the dark kind). G'day primates! You may want to use a measuring cup with a spout or a funnel. Fill the bottle up about 1/4th (1 quarter) with water. This can explain why oil and water don’t mix.

You can try building a density column using only colored water. Instead, a layer of ice forms on the surface, leaving liquid water underneath. A simple science experiment that introduces scientific investigation procedures and uses common, everyday objects to help your students investigate the properties of liquids. Lava lamps are simple to make. Real lava lamps use a polar and non-polar liquid just like our homemade one did. This is because water molecules are packed more tightly; a cup of water actually has more mass than a cup of oil. Try stacking hot, cold, and room temperature water, or try building a column with salt water, sugar water, and fresh water. The water/gas combo is less dense than the oil, so they rise to the top of the flask. Bottom line? But Home Science Tools' products and service can handle it.
