Gel packs stay cold for 20-40 minutes, also depending on its environment.
How cold does an instant ice pack get?
When you hit the cold pack, it breaks the tube so that the water mixes with the fertilizer. This mixture creates an endothermic reaction — it absorbs heat. The temperature of the solution falls to about 35 F for 10 to 15 minutes.
Can you reuse instant ice packs?
