It's up to you to come up with a story about how you put it in there, but here I will show you how to grow one inside a bottle for your very own.
Step 1: Gather your parts
an empty bottle (clear glass is best)
string, twine, rope of some sorts
a pear tree
alcohol of choice (no wine or beer, and mostly clear types work best)
Step 2: Pick your Pears
Step 3: Clean leaves, add bottle
Make sure you support the bottle as best you can with the string, and tilt the opening down so that water won't pool up in it and make the pear rot.
