The Magic Mirror Egg

Magic mirror egg may I ask, what’s it like inside that glass?

How it looks:

This trick requires the use of an open flame, so you MUST have an adult helper at all times for this.

Light the candle and using the metal tongs, hold the egg near the flame to cover it with soot. When the egg is covered in black soot, remove the egg from the flame and blow out the candle.

Gently immerse the soot-covered egg into the glass of water and it should gain a silver-mirror appearance.
You MUST have an adult helper when using an open flame!

What you need:

  • 1 egg
  • 1 candle
  • Matches or lighter
  • Metal tongs with non-heat conducting handles (such as plastic)
  • 1 clear jar (clean jelly, olive, or pickle jars work) or glass (just enough to cover the egg) ¾ full of water at room temperature
  • Counter or hard surface
  • Adult helper



Have your adult helper light the candle. (Make sure to light the candle in a safe place, somewhere that if the candle were to fall over, nothing would light on fire. A kitchen counter might be a good place or outside on the cement.) Hold the egg near the flame using the metal tongs. Your egg will start to turn a different colour. Work your way around the egg to cover it in this dark colour, called soot. Once the egg is covered, remove the egg from the candle and blow out the flame. Let the egg cool to room temperature. This will take about 10 minutes. Place the egg in the jar or glass of water. Your egg will gain a silver-mirror appearance.

How it works:

The carbon in the soot repels the water and holds a thin film of air on the egg’s surface. This layer of air underneath the black soot layer gives the egg a reflective, mirror-like surface.

Did you know…

Using a mirror or other reflective surface to predict the future is called scrying (rhymes with “crying”). It comes from the English word “descry” meaning “to make out dimly” or “to reveal.”
