πŸ₯š The Obedient Egg

Ooh, a good one. Here's what they'll see.

What your audience sees

An egg sinks to the bottom of a glass of water. You order it to rise, stir in a secret ingredient, and it climbs up and hangs halfway, doing as it is told.

A potion is for looking at, not for drinking.

Questions about this

How do magicians make things float?

On a big stage, floating uses hidden supports, careful lighting and angles that stop you seeing what's holding the weight. Close up, it's usually a finger or a thumb you can't see from the front. That's why a floating trick works from one direction and gives itself away from the side.

How do magicians do their tricks?

Magicians use secrets. Some secrets are hidden objects, some are special ways of holding things, and some are clever maths. The biggest secret of all is attention: a magician gets you to look at one thing while the secret happens somewhere else. Then they practise until it looks like nothing at all.

The Obedient Egg for kids: the whole trick

An egg sinks to the bottom of a glass of water. You order it to rise, stir in a secret ingredient, and it climbs up and hangs halfway, doing as it is told. It's a level 1 apprentice trick for ages 6 to 11 (grades 1st–5th), takes 5 minutes to learn, and needs 4 things you already have. Flick, the shop's rabbit, reads every step aloud with a picture, so a child can follow it alone.

The secret

Salt makes water heavier, and heavy enough water holds an egg up. The stirring is the trick; the ordering is the show.

What you need

  • An egg
  • A clear glass or plastic cup
  • Water
  • A pinch of salt

How to do it

  1. Fill the glass with the water and lower the egg in. It sinks.
  2. Order the egg to rise. Nothing happens. Look unimpressed.
  3. Stir several big spoons of the salt into the water, round and round.
  4. Ask the egg again. It floats up and hangs there.

Magic words to say

β€œEggs are stubborn. This one and I have an arrangement. Rise. ...Rise. Hmm. He's new. Let me have a word with the water instead.”

Pro tips

  • Pour fresh water gently on top at the end and the egg hangs in the middle, between the salty water and the fresh. That is the best version and it is worth the extra minute.
  • Talk to the egg, not the audience. An egg being told off is funnier than any patter you could write.
  • Wash the glass well afterwards, and put the egg back in the fridge or in the bin.

If something goes wrong

If it will not rise, keep stirring and say "he's thinking about it". It always rises in the end; it only ever needs more salt.

Safety notes

  • A potion is for looking at, not for drinking.
  • Sit at a table.
  • A bit messy.
  • No fire, no flames and nothing sharp in a child's hand anywhere in the Magic Shop. Nothing ever goes in a mouth, a nose or an ear.

The science behind the trick

Whether something floats depends on how heavy it is compared with the water it pushes out of the way. Salt dissolved in water makes every spoonful of that water heavier, and once the water is heavier than the egg, up the egg comes. It is why swimming in the sea is easier than in a swimming pool.

What kind of trick is this?

πŸͺ½ Levitation. Something floats. Almost every trick ever invented is one of eight kinds, and knowing which one you're watching is how magicians work out how a new trick is done.

The skill it teaches: Patter: what you say. A trick is a story, not a thing that happens. Perform it and it counts towards the Kitchen Alchemist badge.
