Pencils and utensils
1) Step 1: rotate your right hand so that your four right fingers are between the thumb and index finger of your left hand.
Step 2: place your right index finger on the pencil and twist it round in a clockwise direction, whilst bringing your left thumb around your right thumb.
2) A magnetic rod will have positive charge at one end, negative charge at the other, and no charge in the middle. So, move one of the rods so that its end is touching the middle of the other rod, as if to make a T. If there is no attraction between the rods, the ‘stem’ is not the magnet, but if there is an attraction, the stem is the magnet.
3) The dentist puts on both pairs of gloves to treat the first patient, and then takes the outer pair off. She treats the second patient with the gloves that are still on. The assistant turns the gloves that the dentist is no longer wearing inside out, and puts them back on the dentist, who is still wearing the first pair of gloves. The two contaminated sides are in contact, leaving the sterile side on the outside, so the dentist can treat the third patient.
