If you’re lucky enough to have not one but two robotic vacuum cleaners at home, they can make beer pong in our back garden extra fun — and especially challenging.
Put the two Roombas on separate tables, cover them in red Solo cups, and start their cleaning routines. The edge detection that prevents the robo-vacs from falling down stairs will ensure they don’t roll off the edge of the table. The competitors are more likely to fall over by the end of the game than the Roombas are. [YouTube]
