Not the one I have. This is a mystery. Ordered my acid off the Bay. Maybe here by Thursday. One bar to test. Funny thing about ordering from the Bay. The distributor won't ship US Mail but off the Bay they will. The $9.99 bottle with free shipping. I wouldn't saw into it but drill a tiny hole into the side and use a wax dam to contain the acid. Have your water handy and be well ventilated. Kitchen vent on full blast. If the bar starts smoking drop it into the water. I drill holes with my X-acto blade. Slowly as not to brake the tip.
