I've just discovered something.
I had one lodged this morning. Tried ear buds and couldnt budge it. It was really annoying me.
Kids had mcds yesterday and one of them had put an unused paper straw in the drawer. It was perfect for getting the stone out. I just encircled the stone with the end of the straw and gently pushed and it popped out into the straw!
Ita strong enough the put pressure on but only paper so it doesnt scratch or cause damage like a metal or plastic one would.
Little gross but its the fastest Ive ever been able to get rid of one.
