I’d give laser pointers to Neanderthals. Even if they did figure out some useful application for them (maybe hunting?) they’d run out of batteries eventually.

    I would take a portable CD player, place a CD with Rick Astley’s Never Gonna Give You Up on it playing backwards, hook up solar panels, remove the ability to shut it on/off, and set it up a circuit that will:

    • As the device solar charges, keep it off until some voltage threshold is exceeded
    • Once the voltage is high enough, start a random timer (8 - 100 hours), so that it is not immediately obvious that the sun activated the device
    • When the timer ends, turn the music on on repeat mode
    • Sometimes turn the music off at random, and then turn it on again at random after a long delay, so that in some cases you can have turn ‘ON’ events without the device being exposed to the sun
    • When the voltage drops below a low threshold, turn the device off until it is charged again
