Figure out why only certain things can go through the doors.
Green glass doors is played with a group. A small amount of people should previous know how to play. They will begin by explaining that only certain things can go through the green glass doors and give examples such as, “I can bring the MOON through the green glass doors but I can’t bring the STARS…”
They would then give numerous examples. The key being that only words with double letters can go through the grEEn glaSS dOOrs.
A puppy but not, a dog
A Boot but not, a shoe
The floor but, not the house.
A screen, but not the window
Teeth but not smiles
An earring, but not a necklace.
The words do not have to correspond. The object of the game is for the people that does not know the trick, to figure out why only things can go through the doors.
