I visited a home planetarium.

An unforgettable experience I had yesterday when one of my students brought to my office a strange new gadget called Home Planetarium.

She requested me to close all the windows and switched off the lights too but I let the air conditioning on. It was after 7 PM and it was already dark.

She then operated the egg shaped device that projected countless stars on the ceiling. What a sight! It was beautiful to see the night sky inside a room.

I wonder how it works! I could not understand the concept but what an experience!
