Make Your Very Own Duck Caller
This activity is a fun and simple one for kids and requires very little to execute. Grab a straw and some scissors and a whole lot of air power from your lungs and try making your very own duck caller. Experiment with the world of sound and vibration as you vary the sounds that you can make by simple modifications to your straw. You can even have a little band with your different toned straws. If you are having trouble getting a sound, relax your lips a bit while still holding it firmly between your lips. Don't give up. Once you get the hang of it, you won't want to stop quacking. Get outside and see what kind of wildlife you & your family can attract with your handy duck caller.
How to Make It
All sounds are generated from vibrations. The small pointed that is flat vibrates very quickly when you blow through the straw. You should be able to feel that vibration with your lips. Those vibrations made the cool duck like sound that you heard from the straw.
