People usually throw away toilet paper rolls.
However, it makes sense for a mobile phone owner to keep one handset.
The thing is that this cardboard device can be used as... a “sound amplifier”.
In other words, using a toilet paper roll, you can make music from your smartphone sound very loud, eliminating the need to buy a portable speaker.
Music lovers and party lovers should know about this life hack. And also people who don't hear their alarm clock in the morning.
How to turn a bushing into a "sound amplifier"
First, take a ruler or tape measure and measure the bottom edge of your mobile device.
Take the obtained figures into account when creating a hole in the toilet paper roll.
Cut a "strip" out of a cardboard tube? Then insert your smartphone into the resulting hole!
After that, make a support for the "speaker": just insert a few pushpins into the bottom of the sleeve.
Done! Now you can put the resulting structure on a table or some other hard surface and turn on the music. The sound will be quite loud.
