Students experiment with flour and water to make glue.


Students today are familiar with glue in a bottle. However, they may not realize that their grandparents probably made glue by mixing flour and water. The mixture is also used to make paper mache.


  1. In this experiment, give students a glass of water and about 100 ml of flour. Tell them that they have to figure out how many spoons full of water and flour will make a good glue. Don't give them much more instructions than that, except for procedures on keeping their work space clean.
  2. Newspaper or meat tray are good for students to do their experiment on. They will need some paper to stick together to see if their glue is a success. Discuss what they discovered about the perfect mixture of flour and water.
  3. Have the students make paper mache from their invention. Make the glue mixture a little wetter, and then show them how paper mache is made.
  4. Cut strips of newspaper about 2 cm wide and 10 cm long. Dip one strip at a time in the glue mixture. Make sure the glue mixture completely covers the paper strip.
  5. Take the paper strip and put it on a can. Completely surround the can with paper strips and glue, and let dry. When it is dry, students can paint with water color or temper paints.
