Show your LOVE for science with this Valentine experiment! With several opportunities for learners of various ages, this experiment is simple and satisfying. For the little learners, pouring and measuring can help with fine motor skills, while the older learners can observe density and chemical reactions.
The oil will remain on the top while the water settles on the bottom, because the water is heavier or more dense. Once you add the tablet, it will sink all the way to the bottom, then the chemical reaction will occur. As the tablet and water combine, they create carbon dioxide, which creates bubbles. The bubbles push the water and glitter to the top layer of oil where the bubbles pop and the water falls back down to the bottom.
Fill your jar 2/3 full with vegetable oil.
Fill the remainder of the jar with water.
Pour in your glitter or confetti.
Drop one the Alka Seltzer tablet in and watch the show. When the reaction slows, add the next tablet to continue the fun! •
