Sam entered the bubble and looked at the pods.
There are pods of different sizes and all of them are egg shaped.
The largest are the ones that are eight feet tall and most of them are not giving any energy waves or reactions when Sam watched them with the energy vision. These pods also have don't have any patterns on it. In this category there are only few pods that are showing some signs of energy.
The smaller pods varied from one feet tall to the seven feet tall and all of these have patterns. The larger they became, the fainter the patterns became.
There are some pods of this category which are almost eight feet and the patterns are barely visible. There are very close to the pods that have no patterns at all.
