Introduction

Light an incense stick. Close one end of the syringe using the rubber from its plunger. Now place the incense stick inside at different positions and measure the time it takes to extinguish in each position. Also compare it with the time taken to extinguish inside a 700 ml plastic bottle.

    • Be careful while working with fire - incense stick as well as matchbox.

    • Exercise caution while lighting the candle.

    • Handle scissors with care
