If anyone lost a whole heap of sea urchin spines, please contact me. I found plenty of them while chasing a mates kite when his line snapped after I ran into them.
If you want them returned, feel free to bring tweezers along to my house and dig them out of my foot. [}:)]
Just had a good laugh. I can relate to that.
You've got about 2 months of sore feet ahead, just thought I'd toss that in as well.
If you can't pull them out get some cotton balls and soak them in vinegar then tape it over the spines in your foot, that desolves the spines after about a day. Repeat every few hours. If they're not disolved it will still make it much easier to pull them out. 2 days later you'll be fine
Nice one Krispy54... will try that, I have 6 of the buggers stuck in my foot from Sunday
