Raining Sponge Experiment


Science for kids does not need to be complicated. The simplest of things can be fun & educational. I like doing experiments that require very little set up, clean up & are done with items that are easily accessible. This is about as simple as it gets.

All you will need is a jar, a sponge,
water & food coloring.

I showed Mai the sponge & gave her a little explanation about how the sponge absorbs water. She learned a new word today. “Porous? What’s porous?” We showed her.

We filled up the sponge & rung it out. The sponge will hold water, but only so much before it starts dripping out. We made our sponge into a rain cloud. We added a couple of inches of water to a jar & placed the sponge over it. We filled up a squeeze bottle with water & and food coloring,

My daughter loves anything that requires squirting water. So she had fun with this one for a while. She put her squirt bottle right over the sponge & began squirting over the mouth of the jar. We watched the sponge fill up & the color spread as it filled. When the sponge was full, the colored water began to drip into the jar.

Mai was having so much fun, that she kept going until she filled up the jar. We had to refill our squeeze bottle a few times.
