Ok guys its momo here with another secret in mine craft first things fist get 1.4! you need 1.4 to recode certain ids next make a super flat option the hit customize then click presets !don't click any presets! then look at the box above
change the number after 2x to exactly 36 don't touch anything else! next click use preset then wait a few minutes
break the block under you and then you will find the sacred 36 it can make quick sand just put falling sand in it its a very cool block i hope you enjoy it!
