After the ice hockey is filled with water, there will be a little water droplets overflowing from the ice mold seam. This is normal.
 
The water in the ice hockey mold may be reduced a little bit. This is also okay.
 
If the water is too full and the liquid becomes solid, the volume will increase and it will open the container.
 
There is a sense of cracks, so it is better to reserve 2cm space when filling.
