The ball contains a gel pack internally so while it can be put into the microwave for up to 30 seconds. However depending on the type of microwave used, it can easily overheat so please test heat the ball in steps of 10 seconds. The ball also gets increasingly hotter once its taken out of the microwave so users should try holding the ball in their hands for a few seconds to test if it is at a suitable temperature.
