Have an old bicycle horn that just doesn’t work anymore? Never fear, the rickshaw drivers of Kathmandu have an easy trash hack for you: Use a plastic bottle as your squeezer. Any plastic bottle will do. From toilet bowl cleaner bottles to Fanta, as long as it’s plastic and squeezable, your horn will toot once more.
For the full audio-visual experience, watch this movie (you can fast forward to 5:30) and jam with the rickshaw guys.
