Have a glass of water, salt shaker, small bit of cotton thread and some ice on hand. Try get block ice cubes – round and novelty-shaped ice cubes can work against you.
You:
How about we break the ice, but without breaking any actual ice?
Science can help us defy logic and get conversations going, and you don’t even need to be Stephen Hawking to do it. All you need to demonstrate this are some bits and pieces from around the house or office kitchen.
Have a glass of water, salt shaker, small bit of cotton thread and some ice on hand. Try get block ice cubes – round and novelty-shaped ice cubes can work against you.
You:
How about we break the ice, but without breaking any actual ice?
Put a block of ice into the glass of water and reveal your piece of cotton thread.
You:
I don’t want to do all the work… so if you don’t mind taking this piece of thread and using it to lift that block of ice out of the water without touching the ice with your hands.
The person should be game, but won’t have much success in trying to figure it out.
You:
I don’t mean to be cold, but your ice fishing technique isn’t great.
Once they’ve finished trying to figure it out, ask them to hand over the thread.
Lay the piece of thread along the top of the ice floating in the water, the more surface area of ice it touches the better.
You:
My doctor said I should avoid salt, but this is a special occasion
Sprinkle some salt along the top of the ice, covering the thread and ice. Give it a few moments to bond.
You:
Now through the power of science and, er, salt… behold
Gently lift the thread upwards. If you’ve gotten your bond correct, the block of ice should lift effortlessly from the water – stuck to the thread.
Some extra lines you can try
Get all onlookers to have a go for themselves. Have a competition to see who can use the least amount of salt to lift an ice block
I thought you were trying cut down on salt?
Is this how you prepare for ice fishing?
Does that work with any kind of ice?
