Olja + vattenkemi

My kids kept replaying the experiment where oil and water refuse to mix — the visual is oddly mesmerizing. The kit's guide made it easy for them to follow along without me hovering, and the supplies were all there, ready to go. We've done it three times already and they still ask for more.

My 7-year-old asked to do this one three times in a row, and I actually learned something new about oil and water density myself. The activity guides make it easy to set up with stuff we already had in the kitchen.

The experiment cards are laid out so clearly that my eight-year-old could follow along without me hovering. We must have done the oil and water test four times just watching the droplets dance, and she's already asking when we can grab the next kit.
