MAGNETISM GAMES: MAGNETIC REGATTA

MATERIALS:

·         Two 40 cm long rods

·         Two magnets

·         Two 30cm long threads

·         Needles

·         Coloured paper

·         Scissors

·         Six cork stoppers

·         Tooth picks

·         Adhesive tape

·         A big water container

·         Water

INSTRUCTIONS:

1.       Make two “fishing rods”: get a thread and tie a knot in the rod and tie another knot in the magnet. Use the adhesive tape if it’s necessary.

2.       Make two little boats: join three cork stoppers with a toothpick.

3.       Put two needles in the central cork stopper. Use adhesive tape to make the sails with coloured paper.

EXTREME CARE IN THE USE OF NEEDLES.

4.       Fill the container with water and make the boats float. Use the rod to move the boat.
