Place sliced and seeded watermelon into vacuum bag.
Place vacuum bag into chamber vacuum sealer and pull a full, 100% vacuum on the fruit.
If using immediately, remove from vacuum bag and serve.
If saving for a later time, the compressed fruit will remain compressed for a maximum of two days. After two days, juices will start to expel from the fruit, surrounding the fruit in the vacuum pouch. The fruit is usable, but less desirable.
