Leave the sponge out in open air for a day or so. It should dry just fine on its own. If you're in a major hurry to dry it, you could dry using a blow-dryer.

When squazzing a sponge dry, it involves both a push and pull motion. The push motion is squeezing the water out of the sponge, while the pull motion is drawing the excess water into the sponge itself.
Solution
A dry sponge is hard because the water has evaporated, leaving the sponge's cellular structure collapsed and less flexible. When water is added, the cells absorb water and expand, allowing the sponge to become soft and flexible.
He has a fear of dry sponge.
The mass of a dry sponge can vary widely depending on its size, density, and material composition. Typically, a small, standard kitchen sponge weighs around 30 to 50 grams when dry. Larger sponges, like those used for bathing or cleaning, can weigh significantly more. To determine the exact mass, it's best to weigh the specific sponge in question.
Evaporation
A sponge can be both soft when wet and rough when dry.

The object described is likely a dry sponge. When a dry sponge falls on the ground, it retains its shape and does not break due to its porous and compressible nature. However, when a dry sponge falls into water, it absorbs the water and becomes saturated, causing it to lose its structural integrity and break apart.
Yes, he deliberately left the sponge dry, but it is implied -- through his reaction to the execution -- that he did not think it would be as horribly gruesome as it turned out to be.
