Ammonium Nitrate and water.
Urea + plus a Non-Toxic Cooling Additive and Water providing a safer alternative to the dangerous Ammonium Nitrate
*Ammonium Nitrate is highly dangerous and used as an oxidizing agent in explosives.
To make an efficient instant cold pack using ammonium nitrate and water, you can combine them in a ratio of 2 parts ammonium nitrate to 1 part water in a sealed plastic bag. When the two substances mix, it undergoes an endothermic reaction that absorbs heat from its surroundings, creating a cooling effect. Be cautious and use sealed bags to avoid contact with skin as it can cause frostbite.
To keep food cold in ice water, make sure the food is in a sealed container or bag to prevent water seepage. Place the container in a larger container filled with ice water, ensuring the water level stays above the food level to maintain cold temperatures. Replace melted ice with fresh ice as needed to maintain the cold temperature.
To effectively reuse a hot pack for multiple applications, you can follow these steps: Heat the hot pack according to the manufacturer's instructions. After use, store the hot pack in a sealed plastic bag to retain heat. When ready to reuse, reheat the hot pack and ensure it reaches the desired temperature. Use a cloth or towel to protect your skin from direct contact with the hot pack. Monitor the temperature and duration of use to prevent burns or overheating.
If you put a tea bag in cold water, the steeping time needed to extract flavors from the tea leaves would be much longer compared to using hot water. The resulting tea may be weaker in flavor and aroma.
The number of marbles that can fit into a plastic bag depends on the size of the bag and the size of the marbles. Generally, you could fit hundreds to thousands of small marbles into a standard-sized plastic bag.
