Finished your shampoo and disposing off the bottle? Well, they can be put to a better use.
Cut the bottles around the rim and also cut a hole on one side, which is big enough to let a phone charger through.
Wash it thoroughly with luke warm water. Once dry, let the phone charger through the hole in the bottle and plug it in the switchboard.
Let the bottle hang from the charger and place your phone (connected to the charger) inside the bottle.
Now no need to worry about using a charging point without a surface to keep your phone.
