Glass Table

Suddenly she came upon a little table, all made of solid glass: there
was nothing on it but a tiny golden key,...she found a little bottle
with the words "DRINK ME". "What a curious feeling!" said Alice...She
was now only ten inches high...When she got to the door, she found she
had forgotten the little golden key, and when she went back to the table
for it, she found she could not possibly reach it: she could see it
quite plainly through the glass.
