With two coloured strips of paper we will make two interlocking hearts. To make these interlocking hearts you need two strips of colour paper 20-cm x 3-cm, glue, cello tape and scissors. First apply glue in the center of one strip and then stick other strip crosswise to make plus sign. Then stick the two ends of the yellow strip after giving it a SINGLE TWIST in the clockwise direction. Repeat the same with the second red strip. Hold the two ends of the red strip and give them a SINGLE TWIST in the anti-clockwise direction before gluing them. Now we have two Mobius strips twisted in opposite directions and glued together. One strip should be twisted clockwise while the other strip should be twisted in the anti-clockwise direction.  Now cut the red loop completely along its midline. Then cut the yellow loop also on its midline. On opening and arranging the loops you will see two interlocked hearts.
