I like sticking morters in fruit...hear me out now there are two parts of awesome to this....first you get a water melon..cut a hole in it big enough to stick the mortar in, stick the morter in, and lightly replace the square cut out (condenses the explosion makes it better) light the mortar...stand close enough so you are in the blast radius...trust me on this fruit does not hurt and it adds to the awesome of explosion...then and this is important..squish your toes in the water melon remnants its better than any foot massage I swear.
