Learn about science this Valentine’s Day with this fun Valentine lava lamp science experiment! Kids will have a blast with this Valentines STEM activity!
You know what my kids love? Things that fizz and bubble. They are delighted to play with anything that is fizzy.
One of our favorite activities are lava lamps, not only because they are fizzy, but also because they are an easy way to show kids how gasses can move through liquids and make bubbles.
The lava lamp science experiment is a fun way to explain how their burps work, and if your kids are anything like mine, they are oddly fascinated by burping.
Valentine’s Day Lava Lamp Science Experiment
This fun lava lamp science experiment will keep your kids happy this Valentine’s Day! You can make this lava lamp any time of year, but using red and pink colors make it fun for Valentine’s Day science!
Lava Lamp Science Experiment Explanation
Oil is less dense than water, so it remains on the surface of the colored water. Additionally, inter-molecular polarity prevents oil and water from mixing (oil molecules are not attracted to water molecules).
But, when you add alka seltzer tablets, which contain citric acid and baking soda that react when placed in water, creating carbon dioxide. The gas is less dense than either the water or the oil, but the gas bubbles take some of the water with them.
Then, when the gas rises to the top of the oil, the heavier water drops back down, creating a bubbling lava lamp effect.
