You may want to chill your ingredients before hand to help them layer better.
Take your shot glass, jigger and Peach Schnapps. Measure 1.5 oz of Peach Schnapps and then dump it into your shot glass.
Use your jigger again, this time to measure .5 oz of Irish Cream. Put your bar spoon into your shot glass upside down just above the peach schnapps.
Slowly pour the irish cream over the spoon and it should sit on top of the peach schnapps.
Now for the tricky part. Take your Grenadine. Make sure the grenadine has a pour spout built in or you add one to the top.
Slowly drip a few drops of Grenadine into the shot glass. They should sink to the bottom, but not take all the Irish Cream down with them.
Your shot is ready to kick back!
