Unusual Uses for Chalk

Jun 14th 2010 4:03PM as a retired teacher....I have been known to drink too much coffee in the morning, bringing on that 'coffee burn' during classtime. knowing the basic ingredients in chaulk and the commercial acid relief products were similar, many times I grabbed a new stick out of the box, broke off a piece, and chewed it up.....tasted TERRIBLE but worked wonderfully!
