We have unlimited time for bubble activities in this house. Simple, quiet, scientific, quiet…
These are two we did the other day. One was a repeat and the other was found when I googled “bottled lava.” (Oliver happened to have ants in his pants on this particular morning, so the first round of bubbles were a little too subtle…)
Bubbles #1: Fill a cup of water 2/3 full and add some food coloring. Top it off with a layer of vegetable oil. And yes, my son is wearing nail polish… he’s got a big sister so monkey see, monkey do!
Sprinkle some salt onto the surface and see what happens! Oliver enjoyed sprinkling the salt (get the dustbuster ready) and was moderately interested in the ‘lava.’
Onto Bubbles #2. We’d done this last summer and it’s pretty much too cool for school. Pour a few inches of water into a bottle with some food coloring and then fill the rest of the bottle with vegetable oil. (This combo alone is an effective busy bottle for your toddler as simply shaking the two liquids will produce some cool bubbles as the two ingredients go back to their separate corners.)
For the full cool factor, grab some of that alka seltzer you stocked up on after seeing this post. Drop half a tablet of alka seltzer into the bottle; it will sink through the oil and react with the colored water and… pretty pretty bubbles!
This was right up Oliver’s alley as he had a chance to drop the tablet in (“not candy”) and the bubbles were busy enough to keep his frenetic little brain engaged.
Here’s a video so you can get the full effect of this project and all the commentary that goes with it.
What would a rainy day be without Alka Seltzer?!
