Tinkering Trivia: Science Facts & DIY Hacks

For our 3D printed kits, we use a special biodegradable plastic called PLA, which is made from sustainable resources like corn and sugarcane. It's one way we try to create with a conscience.

Here's a quick tinkering hack. If you want super glue to bond faster and stronger, just add a little bit of baking soda. It's a simple chemical reaction that works wonders.

Here's a cool fact: LEDs and solar panels are essentially the reverse of each other. An LED turns electricity into light, while a solar panel turns light into electricity, both using the same semiconductor principles.

Ever wonder how a CD works? It's basically a sandwich of plastic and reflective film with tiny pits that a laser reads as zeros and ones. Here, I break down this fascinating piece of old-school tech.

I once got hotter as I climbed higher up a snowy mountain. The reason is a scientific principle called the albedo effect. The white snow acts like a giant mirror, reflecting sunlight right back at you.

Here's a life hack for you. I built this simple water alarm sensor using some broken plastic bits and basic circuitry to prevent my RO water filter from overflowing. It's a great way to save water.

Welcome to our Tinkering Heroes series. Our first hero is Leonardo da Vinci, a master of curiosity. He designed a parachute and a giant catapult centuries before they were common.

Da Vinci's greatest strength was his sense of wonder. When he wanted to understand something, he observed it closely, took notes, and worked to figure it out, all without formal schooling.

Da Vinci's inventions were incredible. He designed a musical instrument called the viola organ and even built a mechanical knight that could walk and wave its arms.
