Austria invented a new method to enhance the compressive capacity of cans by adding some liquid nitrogen to cans filled with food. As liquid nitrogen evaporates, nitrogen can create higher pressure inside the can, which increases the ability of the can to resist impact and impact. There is also an advantage that nitrogen can displace a portion of the oxygen in the can, thus reducing the possibility of deterioration of the food due to oxidation.
How to apply and store sunscreen
Apply 15 minutes before you go outside. This allows the sunscreen (of SPF 15 or higher) to have enough time to provide the maximum benefit.
Use enough to cover your entire face and body (avoiding the eyes and mouth). An average-sized adult or child needs at least one ounce of sunscreen (about the amount it takes to fill a shot glass) to evenly cover the body from head to toe.
