The poster will present a few of low tech and low cost, but highly interactive and fun lecture demonstrations which can be successfully implemented in a small as well as in a large introductory physics courses. The advantage of these mini experiments is that being cheap and easily prepared these demos can become small take home projects which the students can share with their friends and families. One of these demonstrations is a modified reaction time experiment using a ruler cut out of paper and paper clips; the second one uses a small spring, a string and a weight (or a ball on a rubber band) to demonstrate the difference between weight and apparent weight; the third one is a simple modification of a Greek Waiter Demo using paper coffee cups and a string and the last one demonstrates production of sound waves in a tube using bubble tea straws. These small lecture demonstrations can make a big difference and will help every physics instructor make his or her introductory physics classes more meaningful, fun and engaging.
