I have just finished Challenge Accepted #2. A viewer with the username brock star dominoes commented on the last Challenge Accepted video (youtube.com/watch?v=THg8AwqGl6Y&feature=c4-overview&list=UUBAeMA1Tb6eYkpcvF8sNIKQ) that I should use a bowl for my next video. So, I have. Here is the kind of bowly chaos that ensued from this challenge!

![Machine Screenlink Clip Contest [CLOSED]
Happy 2015 everyone! To kick off the new year, I decided to do something I have never done before: host a contest! For this contest, you must create a Rube Goldberg screenlink clip similar to the clips I made in the Dominoes vs. Rube Goldbergs screenlink collaboration with StarRider (https://www.youtube.com/watch?v=4Wgl6OHfW8g&list=UUBAeMA1Tb6eYkpcvF8sNIKQ). To impress me, your clips should be precise, complicated, or both. Domino clips are not allowed. The contest is open until the end of February. Below are the rules.
Rules:
1) There is no time limit!
2) Do not make an entire Rube Goldberg machine, just one main idea.
3) The camera cannot move, just one single still camera angle.
4) Clips must enter and exit with any of the following materials:
1. Red Domino Rally pivot tracks (highly preferred)
2. Trains and train track
3. Ping pong ball or golf ball on Hot Wheels track
4. Rolling ping pong ball or golf ball
5) Only one entry per person.
6) Do not edit the clips. Leave them the way that they were recorded. (This includes music!)
Once I have all the submissions, I will take all of them and edit them together into a screenlink, with the winner of the contest as the last clip in the screenlink. (Second place will come second to last, third place will come third to last, etc.)
To submit your clip, title your video jackofallspades98 Contest Entry. Then, leave a comment on this video with a link to that video, so you know I cant possibly miss it!
Prizes:
3rd Place:
-subscription if I havent already
-subscription from my personal account
-spot on my featured channels sidebar
-I will take your idea for an Is It Possible or a Challenge Accepted video
2nd Place:
-subscription if I havent already
-subscription from my personal account
-spot on my featured channels sidebar
-I will take your idea for an Is It Possible or a Challenge Accepted video
-collaboration opportunity (this will be passed on to third place if you dont want it)
1st Place:
-subscription if I havent already
-subscription from my personal account
-spot on my featured channels sidebar
-I will take your idea for an Is It Possible or a Challenge Accepted video
-collaboration opportunity
-channel intro with your name made out of a Rube Goldberg machine (this will be passed on to second place if you dont want it)
If you have any questions, leave them in the comments below. I will be sure to answer them.
Good luck! Happy building!
Remember, card trick videos on the first Saturday of every month, and Rube Goldberg videos whenever I get around to making them. I try to average about 3 videos a month. Machine Screenlink Clip Contest [CLOSED]](https://i.ytimg.com/vi/aEdZ1zDZJ_w/mqdefault.jpg)

![The Super Bowl 50 Machine ๐
Its the end of the NFL season again, and you know what that means! Another Super Bowl Prediction Machine! Panthers vs. Broncos. Which will the machine choose?

In this machine, I tried creating a trick that I knew would take up most of the table (the many tricks with the swiveling track on the cars). The strategy after that point was building interesting elements to go along with it, and even overlap it, in the case of the falling shoe box and LEGO train.
Not that these are ever easy, but this machine in particular was challenging to build for three reasons. First of all, the swiveling track ideas took up so much room, I was left with only thin surfaces to build other ideas. Secondly, I had trouble coming up with ideas in general. For a few days, my brain refused to think up any cool physics tricks. But the third reason was the hardest to work around. I literally ran out of many of my materials. I had used up most of the useful Knex pieces, and I was almost out of Hot Wheels track. So half of this machine had to be made using other materials, which was not something I had ever had to do before.
But anyway, in the end, I think I may have created my most complex machine yet. Is it more complicated than The jacksfilms Machine? Not sure. But regardless, I am very happy with how it turned out. Aside from the mechanics of it, even the decorations look awesome!

![Is It Possible #14
Is it possible for three balls to be deposited onto three different tracks using a rotating and moving Knex ball lift?
The idea for this machine came way back when I was making RGM16. I thought if I simplified the idea enough, I could put it into that machine. But when I realized that a slightly more difficult version of the idea would make a great Is It Possible episode, I saved it for this!
This machine when together fairly quickly, and I think that was mainly due to the fact that I connected everything with domino & string as I went, rather than making everything and figuring out how to connect it all at the very end.
The hardest part about making this machine was supporting all the tracks. Not only did they have to be supported at heights I dont typically go to, but they also often had to be supported from weird angles or else they would have been hit by the rotating ball lift underneath. This is why a lot of the supports are at strange angles.
Another very strange thing about this machine is that the first weight (the small red ball) actually had to be kept WET for the machine to work! For some reason, when it was dry, it was too sticky, and wouldnt get pushed out of the ball lift properly. So, I kept a cup of water nearby (you can see it in the backgroud in the second angle I showed the machine) so I could dunk the ball before every test!
This machine was pretty consistent. Once I got some small bugs worked out, I was able to get it to working pretty quickly. It only took 22 fails to work, which is really good for an Is It Possible machine.
