Rubber bands are ubiquitous; everyone has them and occasionally uses them. They come in nearly every shape and size; they’ve even become a craft accessory out of which creative shapes can be formed (just google “rainbow loom designs”).
But have you ever stopped to think about how they’re made? Are they made from natural or synthetic materials? You might be tempted to think that they’re some kind of plastic or silicone, but most rubber bands are made out of the sap of rubber tree plants; that sap, specifically, is latex. Trees are “tapped” – a slice of bark removed – every two days, and the latex gathers in bowls attached below the cut. It will flow for an hour or two and then heals over.
The actual process to turn rubber latex into uniform rubberbands is a complex one; it’s a process that evolved over time, trial, and error into a well-oiled machine – literally. To learn more, click on the following links:

As with anything, we should take care to use what we buy, and buy what we’ll use. Rubber bands are produced by the millions each day (the factory featured in the YouTube video produces 40 million per day), so use the ones you have wisely!
