Hairball
Glass used: Collins glass
1/3 glass hard Cider (Woodpecker)
1/3 glass Guinness stout
1 oz Irish whiskey (Bushmill's)
Fill 1/3 of the collins glass with cider, then float the Guinness ontop, to bring the volume to 2/3 full. Pour Bushmill's in a separate shot glass. Drop the shot glass into the collins glass and slam it!
