Dad teaches 10-year-old daughter how to design and cast a pewter ring

DkJE6n

Designer Ivan Owens showed his daughter how to use Tinkercad to design a ring, print it in PLA plastic on a 3D printer, make a mold, and use the lost wax casting process to make a pewter butterfly ring.

My 10 year old daughter wanted to learn how to make her own metal ring by melting down the metal herself. …The video shows her learning to design and fabricate her own metal ring via sand casting using 3D design software, a 3D printer, scrap pewter, blowtorch, hammer, anvil, vise, drill & various other tools. I provided knowledge and supervision, but she drove the process. Through this process she learns that hazardous materials, such as molten metal, can be safely manipulated using the right equipment and techniques. She wanted to make a video of the process so that other kids could see all of the steps that go into making an everyday item like a ring.

Printed circuit board masking tape

A must-have for the with-it cyberpunk, and it's appropriately hard to get ahold of, being sold only through a Japanese website that uses translation-software-resistant graphics of Japanese text set against an animated background that made mincemeat of all the Japanese-English OCR software I tried it on (I think this is the orders page, but couldn't get more than one word in four out of Google Translate's photo-text converter).

A cocktail inside a hollow ball of ice that you shatter to drink

Cocktail Chemistry explains the drink's mechanics: you create an iceball using a cheap latex ice-sphere mold, melt a hole in the top with a soldering iron and extract the water from inside with a syringe. Freeze the ball in a tub until you're ready to serve, fill it using a funnel, and garnish with citrus peel -- serve in a rocks glass and smash with a small mallet. (via Neatorama) Read the rest
