Right here’s a DIY trick that drew our consideration: a way invented by an individual named NightHawkInLight, who enjoys engaged on small DIY science tasks in his spare time. No pricey devices are vital right here; simply a mixture of Portland cement and foam he created himself. To start, take some xanthan gum out of your native grocery store’s baking aisle, the factor you employ to thicken sauces. To forestall the gum from turning into lumpy, mix 15 grams with a small quantity of rubbing alcohol. To get the most effective bubble exercise, add 60 ml of dishwashing liquid (blue often works properly), then a litre of water. Stir every part collectively and let it set for 5-10 minutes till it thickens right into a gel-like consistency.
The xanthan gum does a superb job of stabilizing the cleaning soap bubbles, permitting them to resist the moist cement with out instantly dissolving. Subsequent, add the cement. You’re searching for a mixture of two elements dry Portland cement and one half gel. At first, every part seems dry and crumbly, however hold stirring and the cleaning soap will start to seep in and whip up some air.

It begins out fairly arduous, virtually like a meringue, however you need to cowl it with plastic or a moist towel for a day or two to stop it from drying out too quickly. Per week or so later, every part ought to be rock strong. What’s actually fascinating is {that a} block that was imagined to weigh 50 kilos ended up weighing solely 22, however it’s practically as highly effective as a strong rock.
