What is the best way to pack sandwiches to put in a cooler? We'll be packing them around 8am and eating around noonI usually pack them in a zippy bag when I put them in lunch boxes, but they usually turn out cold and a little soggyTips? Thanks a bunch!
Thin layer chromatography(TLC) is a technique to find the dyes in a specimen.It is used in forensics to identify a certain piece of clothing be cause paint or dyes differ in chemical composition, even the ones that are supposed to be completely similarThis usually does narrow the range to a much smaller amount.
usually food remains fresh and crisp when you wrap them in aluminium foil.so wrap it with it and then put in a zippy bag
