Did you know?
Did you know that an interesting experiment can reveal whether an aid has expired or not? If you have an old aid lying around, you can easily check its expiration by conducting a simple test. Placing the aid in warm water triggers a fascinating reaction. If the aid contains carbon dioxide (CO2), it will cause bubbles to form in the water. This happens because expired aids typically have a limited shelf life and the chemical reaction inside them produces CO2 over time. So, the next time you find an aid and wonder if it's still usable, try this experiment to determine whether it has expired or not!
