This experiment will work only if her sandwich bag has no holes. Test the bag through half-filling it with water, zipping it shut, and transforming it upside under over the sink.If no water leaks out, you space fine. Empty the end the test water.Tear a sheet of file towel right into a square measuring around 6 customs by 6 inches.Pour the baking soda ~ above the facility of the document towel, then fold the towel into an “envelope” v the powder inside it.Pour the vinegar and warm water right into the bag.Then, carefully but quickly, include the document towel “envelope” to the bag and seal it.Shake the bag a little, then put it ~ above the ground and stand back.The bag will certainly inflate and then pop through a to solve bang.Measure exactly how loud the bang is utilizing the application for measuring volume in decibels top top the iPad in dBA and also record the measurement.Repeat procedures 3- 9 through balsamic vinegar and also record her measurement.Repeat procedures 3-9 utilizing white wine vinegar and record your measurement.Compare your results.
