After having made the mould, they put a short stick in the middle of the mould to create a[br]hole in the cast. The students then mix plaster of Paris powder with water and pour it into the[br]mould. They need to knock the filled mould on the table to remove bubbles and to smoothen the[br]surface.[br][br]LESSON 2 [br]After the cast has set, the students remove their pieces.[br][br][/td][/tr]
