Step 1: Tools
Copper wire. 24 gauge and about 6 inches
Ice pick - to poke a whole in the shell
Step 2: Wire the drill
Inserted into a cordess drill.
Make sure to put a curve on the wire.
And insert the wire ALL the way in.
Drill on High about 30 - 45 seconds, pulling the drill in and out only about an inch and then back in.
It easy to crack the hole - so use a steady hand.
Step 4: Hard Boil
I put the egg in very hot water, bring to boil for 3 minutes and then remove from heat and let sit till water is cool.
I use almost boiling water as to seal the hole in the shell as fast as possible.
But any way you want will work
