In dealing with my refrigerator door battle, I stumbled on Still Tasty, a handy website that helps demystify how long foods last. Here are their guidelines for how long you can keep opened containers of common condiments (commercially produced, not homemade) in your refrigerator: BBQ Sauce: 4 months. Capers: 1 year (brined)
Ball pen is one of the mediums use in writing that comes in  different appearance such as colors, length and ball point. The  first ballpoint of the pen invented was like a â¦ leather tanner  issued on 30th of October 1888 by John J. Loud.
It had a sponge-tipped handle and was filled with different paint colors. These marker pens were not commercially viable and didnât sell. In 1944, Walter J. De Groft patented a marking pen that held ink in liquid form in its handle and used a felt tip. This is the patent that will become a âSharpieâ pen in 1964. First modern (and usable) marker pen was Sidney Rosenthal's âMagic Markerâ which he invented and started selling in 1953. This marker had glass tube of ink for a body and a felt wick and its name comes from a fact that it was able to write on any surface.
