A Piston Glitch

CREEPERLORD--~~~~Get a block of choice,redstone,restone torches,and both sticky and non-sticky pistons.
Place two blocks down touching,then you place redstone down on top of them,on one side of the blocks place two redstone torches.Place blocks on top of the torches and you should have an ifinity timer,if
it doesn't flicker then you have done it wrong.Place sticky pistons on the edges of the blocks as in
it should have the pistons on the short sides of the flickering machine facing upwards.Put the regular
pistons on the blocks above the torches facing the side of the thing that pushes on the sticky pistons.It should have them glitching through eachother when the flickering machine is on.

If you want to destroy some gravel/sand that is in your inventory that is useless then place it on a block
above the glitching pistons so it will fall in the glitching pistons.It sometimes doesn't break them
but it can sometimes push it out and make floating gravel!!

NOTE:For breaking the gravel/sand you have to place more than one block to fall into the pistons and
it will break only all the gravel/sand except one that helps both glitches.
