When you’re on the go (yes, that pun was intended!) and you need a super-simple speaker for your iPhone, try this hack that’s about as cheap and easy as it gets: make a speaker from a toilet paper roll!
You’ll need an empty roll. Use a knife to make a cut the size of your iPhone width and place your iPhone in it. Put in a pushpin or two to keep the roll from, well, rolling.
iPhone speakers aren’t the only thing you can make with this little roll. Check out these clever ideas on Pinterest–taking toilet paper roll art to new heights.
