Pouring an ice cube using supercooled water:

The temperature of the liquid water is reduced below its freezing point, without becoming a solid. The ice wont form without the presence of a nucleation point (a crystal or impurity around which an ice crystal can begin to grow). However, on contact with another surface, the water instantly freezes. Check out how to make instant ice at home in this video: http://youtu.be/sBFK5-JvBAc

Stretching Canvas

Why?
Painting on canvas can be costly, but you can achieve the same effect by repurposing some old fabric. Plus you’ll get great satisfaction from building your own foundation to paint on. Sort through some old clothes to find a t-shirt for your “canvas”, make sure it’s big enough to fit around your frame, cut down the excess fabric, and staple it on. There’s a finesse to finding the right tautness to your canvas, making sure not to leave it too loose or pull it too tight. From there all it needs is a few coats of gesso, and you’ve got a blank canvas to make a masterpiece on.

What else?
By repurposing old fabric, we can build and stretch a new canvas to use for painting. Consider the environmental impact made by repurposing objects that otherwise might just get thrown away. More curriculum connectors can be found here.

Taking off from the water is no easy feat!

85 million years ago, when central North America was covered by a seaway, Pteranodon longiceps roamed the skies. Perhaps one of the most recognizable pterosaurs, its long, backward-pointing crest and immense size (a wingspan of up to 20 feet!) have made it a favorite for generations.

The Kid Entrepreneur

Four months ago Ogel posted a handmade cardboard display for his patches and solved an Entrepreneur challenge in the process.

The response from the community was overwhelming – every one wanted a patch display, too. Sensing an opportunity,  Ogel made a plan to design and produce the displays to sell in the DIY Market.

During two months of development, Ogel iterated the design so the displays could tile infinitely, and he found a local shop that would laser cut the cardboard for him.

We’re happy to share that Ogel’s invention is now the top-selling product in the DIY Market! It’s available for $10.

Help your kid unleash their big ideals to the world by encouraging them to try the Entrepreneur skill.
