Final answer:
To prevent bits of the coals from sticking while walking on red-hot coals, it is ideal to have sweaty soles and to walk quickly. These factors help reduce the risk of burns.
Step-by-step explanation:
To prevent bits of the coals from sticking while walking on red-hot coals, it is ideal to have a layer of sweat on the soles of your feet. The sweat acts as a barrier between the coals and your skin, reducing the chance of the coals sticking and causing burns.
Another factor that can help prevent coals from sticking is the speed of movement. By walking quickly across the coals, the contact time between the coals and your feet is reduced, decreasing the chance of bits sticking and causing burns.
Overall, having sweaty soles and walking quickly can help prevent bits of the coals from sticking and reduce the risk of burns while walking on red-hot coals.
