Snowball Machine Gun

NASA scientist Mark Rober shows us how to make a Snowball Machine Gun that can fire 13 snowballs in .5 seconds. It’s a must have in any self-respecting Uncle’s arsenal.

NASA scientist Mark Rober invites champion card-thrower Rick Smith, Jr. over for some trick shots, and because he’s Mark Rober, challenges him to a face-off with a card-throwing machine gun he made.

NASA scientist Mark Rober gets into the physics of rock skipping, and because he’s Mark Rober, he also build a rock-skipping robot!

TheBackyardScientist says, “My brother and I decided to make an old school video back at the old backyard! we poured molten aluminum on some glass cubes and spheres to see what would happen, and to get some cool slow motion footage. We also melted glass and aluminum together to see if they would mix. Its unfortunate the glass sphere melted and fell over in the kiln, oh well, it was still interesting!”

NASA scientist Mark Rober says, “Five designs guaranteed to win 1st place or your money back. I hope you enjoy the video and learn something new like I did when I made it. Feel free to share with any one who likes to learn science or is in a High School Physics class!”
