Flying Machines in Bedrock!

Egg Blocks, the semi-sticky blocks, brings Java behavior for your sticky pistons.

In Minecraft Java, a short Redstone pulse to a sticky piston will push a block without pulling it back.
In Bedrock, the piston will always pull the block back.
There are many Java machines that make good use of this behavior that are complex to reproduce in Minecraft Bedrock.
The Egg Block emulates the Java behavior, allowing for machines such as a very simple bi-directional flying machine.

3 New Blocks

Egg Block - crafted from 9 eggs
Century Egg Block - an alternative to the Egg Block
Preserver - leaving an Egg Block inside a Preserver will eventually form a Century Egg Block.

Technical Features

Both the Egg Block and the Century Egg Block are sticky when pushed or pulled by a piston, but not to each other.
All blocks, including the Preserver, have a 3-tick cooldown after being pushed.
During this period, the block is immoveable; it cannot be pulled or pushed.

For those wishing to make a 5x5 or larger door, then I suggest this simple tutorial here: https://www.youtube.com/watch?v=3_DjEycFMXQ

I reproduced this by swapping out Century Egg Blocks for Slime Blocks, and Egg Blocks for Honey Blocks.
Finally, the trigger from the button to the single Observer near the bottom was reacting too slow for the lower piston, but this was easily reectified by swapping in a Redstone Block (see picture).
