It’s a long climb down. Infinity mirror coffee table

one-way mirrors are (effectively) equally see-through and reflective on both sides. They become one-way by having the light from one side overpower the reflection on the other side. In this case, the lamp inside the table is brighter than your reflection looking down at the table. If you turn off the lamp in the table and turn on a lamp in the room you’re in, you’d see your own reflection and the ‘lamp’ would see you.
