DIY: Ice Capades
Next time you invite people for dinner instead of going for a traditional centerpiece create something intriguing like a sinking ice display! We all know that ice floats in water however if the water is heavy, we can get the ice to sink.
“Bet that you can magically make an ice cube sink. Grab one from a glass of special cubes you’ve strategically placed nearby, and drop it into a cup of ordinary water. Collect your guests’ money.”
“The key to the trick is heavy ice. Many terms shouldn’t be taken literally a red quark isn’t red, a peanut is neither a pea nor a nut-but heavy water is exactly what it sounds like: water that weighs more than normal. This is possible because elements occur in several different forms, or isotopes, made up of atoms with the same number of protons and electrons (which determine their chemical properties) but a variable number of neutrons(which contribute weight but not much else).”
