A while after I finished my sixteenth step, I realized once again that something on my sketch wasn’t going as planned. On my sketch a lego was going to hit a key on a computer which says “Hey siri call home.” It turned out that the lego wasn’t strong enough to press the key. After some inspiration from you tube, I figured out what was strong enough to press the button. It was a gauss gun. The gauss gun is just a ramp with magnets and metal balls. Magnets are placed throughout the track with two or three metal balls behind it. What’s supposed to happen is that a metal ball will roll down the ramp and it will get sucked into the magnet, and the force from it getting sucked in will free the farthest marble from the magnets force. The farthest marbe from the magnet will come out with tremendous speed.

The last marble will shoot out and will fall into a funnel and the marble will hit the key on the computer. The only problem with this is that the last marble that came out had so much force, it would literally knock the funnel over. The solution to this was having a bigger marble at the end so it came out with less speed. The gauss gun wasn’t just a solution, it looked way cooler.

Now I am on step 24 and I hope that I can finish the remaining steps and get a success, when I film my Rube Goldberg.
