How to obtain a Dragon Egg

Trying to get a Dragon Egg is like trying to get Bedrock (which is actually impossible to obtain in Survival), one of the simplest ways to obtain a Dragon Egg is using a Piston or TNT. If you punch the Dragon Egg by clicking it, it will teleport into another place

What you need
-Dragon Egg (That you have not got in your Inventory)
-Piston
-Lever

Step 1: Take your Piston and place it next to your Dragon Egg pointing the direction of the Dragon Egg.

Step 2: Add your lever next to the Piston to make it activate then pull the lever for the piston to move the Dragon Egg.

Step 3: And there you have it, your Dragon Egg can now be obtained by you.
