The Lightest Desserts

A food scientist pours liquid nitrogen over a meringue to freeze it.
This dessert is so light it’s basically made of air! Experimental food design studio Bompas & Parr created ultralight meringues for an exhibition in Saudi Arabia. A meringue is a fluffy confection made by beating together egg whites and sugar.
To make the airy treats, the designers partnered with engineers in Germany who specialize in aerogels. An aerogel is made by removing all the liquid from a material and replacing it with a lighter gas. By making the meringue into an aerogel, they created a dessert that weighs less than a feather! “Meringues look like clouds, and aerogels look like the sky,” says Rian Coulter, who works at Bompas & Parr. “And we’re trying to tie all these elements together.”
An aerogel meringue weighs 1.17 grams. It is 96% air and 1.3% egg whites. The rest is sugar. How much sugar is in the meringue, rounded to the nearest hundredth? Record your work and answer on our Numbers in the News answer sheet.
