How can you heat a hockey puck?

To heat a hockey puck, you can place it in warm water for a short period, ensuring the water isn't boiling, as extreme heat can damage the puck. Alternatively, you can use a microwave by wrapping the puck in a damp cloth and heating it in short intervals to avoid overheating. Another method is to use a heating pad or a heated surface, but be sure to monitor the temperature closely. Always allow the puck to return to a safe playing temperature before use.
