Welcome to Bedtime History. Hello, this is Brack.

Growing up, one of my favorite childhood memories was using my imagination to build new things.

I'd take apart old, unused electronics or appliances in our home, and then try and rebuild them into something new and interesting.

They usually didn't work. They were more like works of art than functioning inventions, but I had a blast doing it.

What's great about a product like KiwiCo is the things you build as part of the engineering kits actually work.

My kids and I have built a few different projects together, including a ukulele, a pinball machine, headphones, and a speaker.

These projects include detailed instructions and also explain the science behind how the devices work.

As a parent, it can be hard to find creative ways to keep your children busy, challenged, and off screens.

KiwiCo does the legwork for you, so you can spend quality time tackling projects together.

KiwiCo also has boxes for geography and culture, the Atlas crate, and another one focused on cooking.

Other subjects are science, art, engineering, crafting, and design. KiwiCo also has crates designed for kids and adults of all ages.

Close your eyes and imagine you are on a battlefield. You are in a trench with other soldiers waiting for the battle to begin.

Night is fallen and you and the others are very cold. You look around at the other soldiers. They look nervous too.

Everyone knows the enemy isn't far away. Above the trench, the sky is filled with dark smoke and small airplanes in battle. You tighten your grip on your rifle.

In the distance, you hear a loud boom. You duck into the trench, as an enemy round explodes above you. You fall over and look at your arm and realize you've been hurt.

Other soldiers on your team have been hurt too. You close your eyes and lie back, wondering how you are going to survive.

Soon someone lifts you up and carries you to a nearby hospital. You lie on a clean bed with your eyes closed. Just hoping you will be alright.

Then you hear a kind voice and open your eyes. It's a woman, a nurse wearing a white uniform with a red cross on the front of her hat.

Everything will be alright, she says, lying a warm cloth on your forehead. She looks at the wound on your arm and starts to work cleaning it.
