What if two plastic boxes are stacked too tightly?

If two plastic boxes are stacked too tightly, there are several ways to open them:

1. Pour water into the gap between the two boxes, and if possible, it is best to immerse it in water, so that water can penetrate into the gap between the two boxes, thus destroying their sealing performance.

2. Find an air gun or any tool that can blow air, press the mouth of the air gun into a flat shape, and then insert it into the gap between the two boxes to blow air in, so that air can penetrate between the two boxes and open the boxes.

If there is sunshine at home, you can put two boxes in the sun to warm up. The accumulated air temperature between the two boxes is slightly higher than the outdoor temperature. If the temperature is high, the internal pressure will be high, and the two boxes can also be separated.

I hope the above methods can help you open two plastic boxes that are too tightly stacked.
