In the west, giant chalk (also known as Sidewalk Chalk) is commonly used by folk artists in street performances. Here we introduce a method of making hard but not brittle quick dry chalk. You can make different sizes and colors of chalk according to this formula. Materials needed: tempera paint, Paris powder plaster, fresh film core tube, wax paper, sealing tape, plastic bag, scissors.

　　1. 將保鮮紙切成12-13厘米的小塊，用蠟紙包起來，一端用膠帶封好，另一端放好。2. 重復(fù)幾個(gè)密封紙芯模具。3.現(xiàn)在粉筆比例和顏色混合:將2到3湯匙蛋彩畫和1/2杯水混合，加入3/4杯巴黎石膏，用勺子充分混合。然后，將混合物倒入塑料袋中，在塑料袋底部開一個(gè)口，將顏料擠進(jìn)一個(gè)有封底的紙筒中。4. 等待粉筆干燥，在室溫下至少12小時(shí)。完全干燥后，從粉筆上取下管子。這樣就做完了。

　　1. Cut the paper into 12-13cm small pieces, wrap them with wax paper, seal one end with tape, and put the other end. 2. Repeat several sealing paper core molds. 3. Now mix the chalk proportion and color: Mix 2 to 3 tablespoons of tempera with 1 / 2 cup of water, add 3 / 4 cup of Paris plaster, and mix well with a spoon. Then, pour the mixture into the plastic bag, make an opening at the bottom of the bag, and squeeze the pigment into a paper cylinder with a back cover. 4. Wait for the chalk to dry at room temperature for at least 12 hours. When completely dry, remove the tube from the chalk. This is done.
