Let's Hand it to Hands: Part 3

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Hey again guys! Today I'll be talking about e-NABLE and my last project. REMINDER: Whoever guessed "A brain-controlled hand" on the question is right. Good job!!!!

In the last post, we left off with a big question: What will happen when Liam grows bigger?

 His fingers would be too small for him when he grows.
This was a big problem for Liam. That's when Ivan got an amazing idea! He could make a bigger design of Liam's hand, turn it into a digital file, and feed it into a 3D printer. A 3D printer scans digital files and it prints three dimensional pieces that the file had on it. Ivan had to add strings to the hand, that's so person can move their wrist to pull the strings! As soon as he put the hand together, he gave the hand to Liam. The hand that Ivan made had worked! YAY!!! With that digital file, they could help even more kids around the world. They soon decided to share their hand design online, for free! Everybody that saw the design wanted to help. The design was used over and over again for kids around the world.

This is the design for the e-NABLE hand. Whenever
a person flexes their wrist, it pulls the strings.
I think e-NABLE also makes prosthetic fingers too.
Did you know that you can have a hand designed
a certain way? This was designed for a kid
who loved Captain America! I wonder if
they have Minecraft hands? ^_^

The last project that I did was called "Try a Touch Test."

I had to tape two pencils together at even length. Then I ran two tests, one on Aidan and the other on Mom. I gently touched their fingertips with the pencils. They felt two pencil tips. I gently touched them with the pencils, this time on the arm. Interestingly, they only felt one tip.
What is going on? Recepters!!! They send a signal to your brain saying you touched something. The recepters are close together on your fingers. On your arm, they are much farther apart. Cool huh?
