Step 1: You Will Need:
You will need:
- 1 flame
- 1 skewer
- 1 plastic pot
Step 2: Heat Up Your Skewer
Firstly heat up your skewer, using the flame, being careful not to burn your fingers as metal is a very good conductor of heat.
Step 3: Make the Hole
Secondly make a small hole in the bottom of the pot (good idea to do this on a protective surface to avoid damaging the worktop/bench/table).
Step 4: Enlarge the Hole
Finally enlarge the hole in the pot so it will fit over the speaker of your phone.
Step 5: Listen to Loud Music
After letting the plastic harden you can now listen to your amazing loud music.
Step 6: The Science Behind It
The science behind how this works is very simple; The pot makes the sound waves more focused which then makes it louder.
