I went to one to help me with an idea for a 7th grade science fair when I was a child and the staff helped me figure out which items I needed, which included a bunch of electronics parts and motors I had no idea what I was doing with. They patiently and very enthusiastically explained to me how they worked, how to safely use them, and gave me encouragement on my ideas for the project. They thought it was a cool idea. I was really blown away. I went on to win that science fair but honestly could not have done it without their help.
I still go back once in a while and love to look at the strange electronics parts they somehow acquired. I definitely love that someone decided to try to collect and sell these things.
