A coin is seen on top of a rubber sheet which is stretched over a clear glass beaker. A volunteer places their finger on the coin and proceeds to push the coin through the rubber into the beaker. No hole is left in the rubber sheet, solid has passed through solid!
Method
The coin through latex trick is marketed under various names, usually Pena Coin, which can be bought for about £5 from Amazon for 3 sheets. Your local dentist or an internet dental supplier may sell small rubber sheets called dental dams which may be cheaper. I got mine from a company called Mr Dental.

Put 10p piece and rest it on a cork or bung. When the rubber is stretched over the coin is becomes transparent and clings to the coin, creating the illusion the coin is on top of the latex when it is gripped underneath. Adding a coin tucked beneath this slightly enhances the illusion. Get a pupil to push to the coin through and they will get a pleasant shock. Check for latex allergies beforehand.
The Science behind
The Science behind
This article shows a real time application of polymers for potentially making smart windows, using a polymer like latex that becomes transparent when stretched. The premise is that the intensity of light passing through the polymer can be controlled by stretching.

The magic trick involves the use of scientific principles, demonstrating how innovation and scientific knowledge can create awe-inspiring experiences. It emphasizes the importance of investing in research, technology, and infrastructure to foster creativity and discovery.
This magic trick can be linked with the study of smart windows made with polymers like latex. These windows can automatically adjust their transparency in response to external conditions, such as sunlight and temperature which can enhance energy efficiency in buildings.
Smart windows, on the other hand can reduce the need for excessive heating and cooling, leading to lower energy consumption and reduced greenhouse gas emissions.
