My Dad did the coolest one for my fifth grade class that everyone still remembers. He showed us how binary addition in a calculator/computer works by giving us all 0 or 1 notecards. Then since the class is already arranged in a grid, each row is a single digit (8 bits). Then He gave input numbers and we raised our cards according to which bit we were an the person to the left of us. Honnestly I don't remember the spe…

#222Not super relevant to your problem, but a fun anecdote: I used to be a game developer at EA Tiburon, the studio that does Madden among other games. Somehow I got roped into giving a short talk to a bunch of visiting high school students. Beforehand I emailed a bunch of game teams and asked them to send me screenshots of their weirdest bugs. I got all sorts of fun stuff. When a game with rendered animated humans goes…

#223Maybe I'm old school but I think it would be neat to bring an old rotary phone and pull out your cellphone and explain how modern phones would be magic to someone 50 years ago! edit: this is probably boring and would not be age appropriate

#227- Things you can automate, e.g. scraping cartoons from the web with a simple shell script
- Capturing insecure web traffic with Wireshark, e.g. making someone post secret data with their mobile phone that you can eventually see
- Show how you can remotely access another computer

So what do you call an engineer that designs/optimises/etc. locomotives?
I'd go with SapporoChris's answer with Mechanical Engineer. Locomotive Engineer's basically are the one in charge of operating the locomotive. What most people think of as a "Conductor" is actually a lower level job and is mostly paper work from what I hear. Source: Close friend is a Locomotive Engineer in Canada.

To enable experimentation like that, I'd like to see mobile browsers include developer tools as well. More and more people grow up using a smart phone as their main computing device, and I think they should be given the opportunity to tinker with that as well. I realize that developer tools are information dense and fitting them on a smartphone screen would require a significant effort to redesign the layout (especia…
You can use Chrome Remote Debugging to access the developer console for a mobile device. https://developers.google.com/web/tools/chrome-devtools/remo... You can also load Eruda with Javascript. https://github.com/liriliri/eruda
The Eruda approach to inject the debug console with a oneliner in the address bar seems like a possible solution, though. Thanks.
