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.

Tonight we're going to learn about the Han Dynasty, which ruled China for over 400 years.

China is located in the east, which is across the Pacific Ocean from the United States, then below Russia and above India.

Like many civilizations, China changed over the years as impers replaced other impers.
