Bombs Away! or Making Moon Craters

Making Craters

Or dropping marbles. Whichever sounds more exciting to your kids.

I’m rearranging things and putting  the activities on Thursdays rather than Fridays, there will be something completely new tomorrow.

This week was very simple – we half filled a plastic container with flour then dropped marbles and balls into it. It was lots of fun, the girls didn’t spend a lot of time on it in one go but came back to it throughout the day.


Flour, a container and several small balls.


Flour is another fun and safe texture for babies to play with. It is finer than most sands and drier than clay, even the big girl was picking it up and running it through her fingers. If they put it in their mouths it’s not only safe but another new experience as they will feel it sucking in the water and getting gluggy.

For older babies, try hiding some small balls or objects and they can find them.

Toddlers and preschoolers

The little girl loved dropping a ball in then pushing it right down and burying it. Then she would look up and me and grin, saying “It’s gone!” before pulling it back out like a magician. Think of it as a miniature sandpit.


Dropping two marbles the same size but different weights.


The big girl got it. She dropped balls of different sizes. She compared dropping and throwing. She dropped balls that were the same size but different weights. She threw at an angle. She loved the beautiful smooth shapes. In other words, she tested and compared and tried to work out how to make different craters.

We didn’t talk much about the moon, which is what I had in mind when we started. But we did talk a lot about size and weight and force. And we had a good time.

This is great fun! I hadn’t thought of using it as a textural experience. Thanks for the idea. 🙂

When I did this activity a few years ago with older children, I sifted a fine layer of cocoa powder on top of the flour. That way, when they dropped things in, it showed the spatter pattern clearly. (This wasn’t my idea, but I can’t remember where I got it from)

I meant to do that with the big girl, but the little one had so much fun diving in and digging around I forgot to! Thanks!

OMG. You were at my place last night!
My 4yo suddenly had a fascination with meteors and craters. We had to get onto the internet and look at some craters as well as meteors on YouTube (very disappointing selection on there, I must say). Anyway, I told him that today we could make our own craters, and I was praying that I would find an old post of yours to help me. Fortunately, as the evening went on, he digressed to volcanoes, and I knew you had a post on those – I’ve just come back from the shops with 2L of vinegar 🙂
Now we can do both, you’re a legend!

Now that is beautiful timing 🙂

I remember doing this as a kid and loving it. Thanks for the reminder! My kiddos will love it.

Hello! I’m always looking for simple science ideas. Love the multi-age options. If it’s okay, I’m pinning this on my Pinterest. Thank you! Kristi
