Why Do Plastic Easter Eggs Have Holes?

This seems to be a pretty big mystery on the internet as to why newer plastic egg styles generally arrive with little holes.  While the speculation goes from safety (holes allow breathing…I feel this one is a stretch since the holes are tiny) to they are for hanging the eggs (not the most common use), the most reliable answer comes from AskingLot:

“It’s to let the air out when you join the two halves together. Seal the holes and try it. They keep popping open!”

I just called this reliable information and then I am going to say…

If your plastic Easter eggs have holes, fill them in with hot glue.  You don’t want holes in your eggs for the Gak slime.  And we haven’t seen any problem with having plastic eggs without holes.

Which takes me back to the question…why??!
