Kids love blowing and chasing bubbles in the park or yard, but those little bottles of bubble solution can get expensive. But, there’s no need to buy those overpriced bubble solutions anyway because it’s super simple just to make your own. Plus, it’s a ton of fun to do it yourself and you can easily get your kids involved.

Here are three bubble solution recipes to try with your kids. See which one works best!

A classic science experiment, adding Mentos to diet soda will produce a huge geyser that will have your kids going crazy with excitement when they see it. They’re probably going to see several videos of this throughout their childhood and they’ll want to try it, so why not be the one to show it to them first and get some cool parenting cred?

Follow these simple instructions to show your kids what happens when Mentos meets diet soda.

  1. Start Your Own Compost Pile

Not just educational, but useful if you have a garden or like to grow plants. You’ll need some space for this one and it’s a long-form experiment, meaning you won’t see results for a while, but you can keep an eye on it throughout the summer to note the changes that take place.

  1. Make it Rain in a Bag

Technically, this is an indoor activity, but it teaches kids about weather and it’s great for a rainy day because you can teach your kids why it’s raining. The great thing about this activity in particular is that you can introduce a bit of artistry, too, because you need to draw a scene for it.

  1. Float or Sink

This one couldn’t be simpler. You just go for a walk somewhere outdoors and collect items from nature like a leaf, a rock, a stick, a feather, a mushroom, etc. And then you ask your child if they think the item will sink or float and record what they say. Take your items home and fill a bucket with water and see whether they were right about which items would float or sink.

  1. Nature Color Hunt
