maybe everyone seen this trick before
but I think this is very
There are many videos about eggs
but I choose this
WHY?
Because this trick combines grade 8 and our daly life
I think it's usefull
This video show us that
after the bottle meets fire or hot
the mouth of it will become wider
and the egg cane go in easily~~
IT'S VERY COOL!!
