Bluetack

I happened to used a bluetack for my physics experiment. While I was carrying out the experiment one fo my group member, told me a story about bluetack. He said during his high school time, he loves bluetack very much. He always go around the school with his bluetack, playing with it. Well, one day during assembly, he saw a bluetack on the floor and due to his playfulness. He picked up the bluetack and enjoy playing. While he was playing, he smells the aroma of a grape. Then, only he realised he wasn't actually playing with a bluetack, but in fact, a CHEWING GUM!! LOL!!
