Baking soda + vinegar. A favorite in my house and a favorite of mine from childhood. The smell of vinegar still brings me back to elementary science fairs and building volcanoes out of mud in my backyard. The reaction between the two ingredients just never gets old. It’s the ultimate boredom buster in my house with my kids despite the seemingly million ways we have already played with it. When we had the chance to check out the PLAYMOBIL Water Park with Slides Playset, it seemed like the perfect time to make an erupting water slide!
The ultimate backyard, summer STEM experiment: an erupting water slide!
After assembling the water slide (a STEM project in itself) we were more than ready to play. The set has two slides, a smaller, curvier slide and a larger, faster slide, perfect for a little prediction and observation. I like to start all of our science experiments at home talking about the scientific process and using words like observation, prediction and experiment, and get butterflies in my stomach when my 5 year old uses these words especially with the lack of pronunciation of the letter ‘r’ (major nerd moment, yes).
If you’ve never done a baking soda and vinegar experiment with your littles, you are missing out. For one, its a super simple setup (and cleanup if contained in a bin or outdoors) and it really never gets old. There are countless ways to play with it including color mixing and even art printing!
We filled the base of the water park, the pool area, with a box of baking soda. Adding a bit of food coloring to our vinegar is always fun, and by using primary colors, you can talk about color mixing and the color wheel while conducting your experiment. Using our handy droppers (medicine syringes, pipettes, etc) we dropped vinegar down the slides and watched as it landed in a pool of baking soda at the base of the slide, erupting in tons of scientific fun! We continued to experiment, dropping different colors of vinegar down the slides and observing the colors formed in our pool. The kids discovered that by sprinkling a bit of baking soda ON the slides themselves, they could observe the reaction trickle all the way down the slide, and voila…an erupting water slide.
