I am delivering a lecture on Cyber-safety Basics. I want to start off a lecture by involving the audience to get their attention.
Example: I want to ask everyone to connect their cell phones to a Wifi hotspot and then get into one of the smartphone and extract a file and show it on the projector. That way I will get their attention.
Can anyone please recommend me a way to do this or any other short trick with Wifi/Bluetooth to stun the audience. It's only for lecture purposes. I have a software "Wireless Network Watcher" which gets the MAC addresses of the devices connected to the same Wifi, but that's not very stunning (I believe) to get the attention.
Any help/link will be appreciated.
