On Friday you created a Rube Goldberg machine that had at least four steps that could pop a balloon. Some groups were successful in popping a balloon and others were not. All groups had failures they had to overcome. Watch the video and then in the comment section share about one problem your group had and how you overcame (or tried to overcome) it.

We had a problem with the doll slide, so we just took it off.

Yeah, that was a pretty good solution since we had 6 steps but we failed anyway.

My group forgot to tape the balloon to the ramp so the balloon just flew up so it didn't pop.

Yeah, I remember your group just needed one more step and when you added them, the balloon wouldn't stay so the balloon didn't explode

I think you should put the thumb tack instead of the nail, because the thubm tack is thinner and it would probably make it easier to go through the balloon

our group just had 3 steps so we needed to add one more. But unfortunately the balloon did not pop.

Alejo that actually was a pretty problem to solve because we just needed to aim right. Sorry if this sounded mean.

We had a problem with the "fancy dominoes" at the beginning so we made it simpler.

One problem was that our whole plan didn't work and we did the whole scetch all over again. Soyoun came to my house at first and we were planing and we had a great idea, but I didn't have the matirials so I went to her house and we had a plan that would totally work.

We had problems with a doll slide like DK said and since we had 6 steps, we took of the doll slide and a bag to trigger it.

Like Sally said, Soyoun went to her house and they changed everything and at the challenging day, I didn`t understand anything in our project! That`s the problem!

We had problems solving how to shape the ball

I agree because the balls were going side ways and even though they hit the skate board it wasnt with much efficiency, but the balloon was the problem and to me it was the most challenging problem.

Our group also needed one more step, so we added the dominoes and the ball turning on the blow drier

I think we did a very good job on it but if we did it again I think we could improve a lot.

The ball didn't hit the car strong to go down the ramp, so we did it

One prob was that the balls didnt go strait so we had to move them a bit.

I totally agre with you because I think if the ball didn't go straight it wouldn't have the skateboard

I went to Sally's house because uor old plan didn't work. Then, we got the ideas of the ball and the car by Olda and rest of them, Sally,my parents, and I had idea. Also, we had many problems on our first on, so we chsnged the plan. Then, the second one, there were problems on hights.

I sort of agree and disagree with Olda because we got some ideas from Olda, evn she couldn´t work with us at our house. The part that I agreed was that sometimes we weren´t focused.
