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.

Come with me, dear listeners, back in time to a land shrouded in mist and jungles and swamps.

A time hundreds of millions of years before T-rexes stalked the earth, growling and rumbling and crashing through thick forests.

A time before teradactals soared through the skies, shrieking, and diving through clouds to capture unsuspecting prey.

It's a land rich with possibilities and emerging life forms, water covers large portions of the earth's surface, and in its depths are fish and sea life of an amazing variety, all-teaming and eating and reproducing.

Everywhere growth and change are happening in open seas, pristine lakes, and murky swamps across the continents.

Some amphibians or fish are growing larger, some are growing fangs, and some are growing legs and becoming tetrapods.

Tetrapods are four-legged creatures with vertebrae or spines, and one of these tetrapods is a murky swamp creature called Crasadgerinus Scoticus, or sea Scoticus meaning thick, Scottish tadpole.

But don't let this cute name and fanciful image fool you.
