Got a crack? A drafty window or moldy shower? Take a trip to Home Depot and you'll discover there's a caulk for every possibility (at every price), along with an arsenal of guns in which to dispense them. But how much of the gooey stuff do you need? Are you really going to clean the gun and store it along with your random box of tools (three mismatched screwdrivers, some electrical tape and a hammer)? Probably not. Which is why GE introduced these little single-use beauties packaged in disposable Capri Sun like pouches that let you evenly do your filling with one hand in a neat bead. $2.50 at Lowes Hardware, as well as True Value, Ace and Do It Better stores.
