11+ DIY Science Projects Using Stuff You Already Have At Home

Diply 24 Oct 2018

Did anyone else spend a ridiculous amount of time in the bathroom as a kid making "potions?" I would actually spend way too long in the bathtub or by the sink mixing all of my parents' and older brothers' stuff. They didn't exactly love that.

Kids are curious, and tbh, I still am. Any time I can be amazed at simple science experiments, I take the opportunity. That's why I watch way too many useless videos on Facebook teaching me weird things I'll never need to know.

But, for those who want some legit science experiments to try with your kids or with your friends, here are some super cool ones I've found!

1. Let me take you back to Diply's holiday gift swap back in 2017.

We played that gift game where people can steal the gift up to a X number of times. One of the gifts that was a hot commodity was a lava lamp.

While you don't expect a bunch of adults to fight over a lava lamp, it does look pretty rad hanging out on my colleague's desk.

You can make your own using oil, food coloring, and an alka seltzer tablet. Thanks to Little Bins For Little Hands for this fun project!

The acidity from the lemon combined with the baking soda create a fun reaction.

With the food coloring, it looks like the lemon is oozing! Super fun for kids of all ages, or if you want to impress a bunch of drunk people at a party.

3. Eggs are definitely an interesting food item to try some experiments with.

Tinker Lab used some egg shells to create a colorful geode, and it definitely looks pretty darn cool.

If you're planning on trying these experiments, you're definitely going to want to get your hands on Borax.

You'll also need some rock and sea salt, as well as something that crystallizes, like sugar.

4. Have you ever wondered what would happen when you put certain things in the microwave?

Our Best Bites put a bar of soap in the microwave and the result was actually kind of neat.

When it's done, you should have a fluffy and foamy substance that kind of resembles a cloud.

You can even use this to make more soaps! Just check it out over on Our Best Bites for more info.

5. What did you think would happen when you put some flowers in some water with food coloring mixed in?

I've also seen it done with celery, which looks super cool.

I can't believe how the flowers soaked up the colors!

You need to put a couple of water bottles in the freezer for around 2 hours and 45 minutes, according to Greensboro Science Center.

After this time, your water should not have frozen but will be pretty darn close.

Fill a cup with ice, then start pouring your cold water over top. Then, you should see your ice grow!

The next part is the simple part!

Just spin the jar in circles, creating a visible tornado. This reminds me a lot of creating "whirlpools" in the pool as a kid.

How on earth did Dollar Store Crafts turn a pipe cleaner into a geode?!

Using boiling water, Borax (told you it would come in handy!), and food coloring, you can create a similar style!

I still can't figure out the science behind it, but I certainly want one of these for myself.

10. Teach your kids the important of sunscreen by having them spread it all over a black piece of paper.

I Can Teach My Child says to then put the paper in the sun for a couple of hours. You'll be able to show them that the paper fades wherever the sunscreen wasn't applied!

But, unlike some (bad) lifehacks suggest, don't go trying a lemon to power your electronics, okay?
