Inflate air mattress without pump
You have to be inventive! A sleeping guest was visiting and we wanted to inflate a really huge air mattress without a pump.
I tried it ...
The guest came from Colombia and picked up a hair dryer from the bathroom. With that we were able to inflate the air mattress at least almost without effort. The rest was easy then :-)
Attention not intended for a permanent solution because the hair dryer was a bit hot. But to use as a stopgap.
