Do you like popping the bubble wrap?
Sorry, This machine robs your pleasure! This is the “Bubble Wrap Popper”.
Maybe it’s more fun to pop the bubble wrap by hand. :-p
Snap! Crackle! Pop! (Sometimes make a mistake.)
Why I came up with this?
One time, I was drunk and talking with my friends.We talked about “What’s a meaningless thing?”.
I thought its meaningless and fun to pop the bubble wrap.
So, I thought of making a auto machine for popping the bubble wrap with LEGO.
This machine is very expensive!
In Japan, usually LEGO only sells full “kits”.In order to get a block that I need, I must buy a kit, but I never build the kit.
I want only one part!
In recently, I use Internet shop that sell in each part. :-)
Structure
This machine is using one motor which supplies electricity from an USB.2 actions are running by that motor, slide a bubble wrap sheet and pop the bubble.

It was very complicated but it was convenient to synchronize the 2 actions.
Decoration
It’s meaningless but important to me. :-)Of course, I requested a operator for operation of this machine.

And warning lights like a factory.

It’s cute and exciting!
About background music
This movie’s background music is “Marche” from The Nutcracker.(Because this machine cracks things!)
Problem
This machine had a problem…The bubble is not always sliding to center of pressure foot (bubble press parts).
![pressure foot](https://i1.wp.com/www.kohsukeslab.org/wp-content/uploads/2015/05/pressure-foot.jpg?resize=400%2C293)
When the bubble wrap was sliding to center of pressure foot, it will be crushed precisely.
But when the bubble wrap was sliding to non-center of pressure foot, it will not be crushed.
The problem cause is difference between distance of bubbles and sliding width.
Then the pressure foot will be not hit a center of bubble wrap, gradually.
However I settled this problem!
I will explain that machine in the next article!
Thank you!
Your article was exenellct and erudite.
