You`ll need : A Mason Jar with lid, reusable straws (I got mine from Starbucks), #14 stainless finishing washers (I grabbed these from Home Depot in the washers/nuts/bolts section), Cropodile (optional), oh and a glue gun!
.Start by punching a hole in the center of your lid (you could also poke the hole out with a hammer and nail if you don`t have one of these fancy little cropadiles), you`ll most likely need to widen it, so you can cut a few more around it to widen it. fill the inside of your washer with hot glue (try not to overfill), and carefully (it`s hot!) place over hole. Repeat for bottom. You`re done!
