Clearly, they are not the only ones, as clips associated with “green glass door explanation” have received a total of 27.1 million views.

To solve the riddle, there is a secret formula that tells you which things can pass through the door, and once you know about it, it becomes shockingly obvious.

The key is how the words are spelt. Words of objects that contain two double letters are allowed through the door, while those without are not.

Under the formula, a daffodil could go through the door, because of the double f, but a tulip could not. Similarly, a sheep could, because of the double e, but a cow couldn’t.

Pretty simple when you know how it works.
