HOW TO MAKE A GIANT STEEL SKELETON HAND

“Bulid your own giant steel anatomic skeleton hand out of junky nuts and bolts! It makes a nice coat & towel rack too. This is a perfect first welding project because you can make lots of mistakes and it will still come out fine.” LINK

Melting steel with the sun

The same science responsible for frying ants is at work on a larger scale in this clip from James May's "Big Ideas" series. What you've got here is a solar furnace, a carefully arranged array of mirrors that catches heat from the sun and reflects it, focusing it to point—effectively taking a lot of disparate, comfy sunbeams and gathering them together in a tight bundle. By their powers combined, the reflected beam can reach temperatures of 3,500 °C (6,330 °F). Watch in wonder and terror as the beam turns a hot dog to char and melts steel.
