Eggs (the larger the better and the harder the shell the better, these are “jumbos”)
A bowl (to catch the egg in)
The egg carton (to store the blown eggs in)
Turn the egg over and repeat the process on the other end of the egg. Stick the awl into the egg and scramble the yolk. A yolk will not go through that size of hole, unless it is broken up.
Use a towel to wipe off any egg white or yolk that is outside the hole.
Bring the end with the smaller hole to your mouth, take a big breath and blow. Take another breath and keep blowing, repeat until you no longer are blowing liquid egg, but are blowing nothing but air completely through the shell.
