Congratulations to Merrie Benjamin for winning the Grand Prize for her entry in the Kids’ Science Challenge Sensational Sounds category. Here’s her entry:

My musical instrument is called the water spritz. It is a group of spritz bottles full of water. If you pull the handle which makes the water come out, the water is sprayed into a cup. Depending on what the cup is made of , it will make a different sound. It doesn’t make the sound if the cup already has water in it. The necessary vibration to make the sound never vibrates if it’s full of water. So I decided to put tubes which lead back into the spritz bottle. The sound is always clear and you never run out of water. The vibration in the water hitting the cup makes the sound. This instrument is also good because recycled bottles make it work, so you don’t throw away the bottles, but instead make a cool instrument. Everything is connected by metal planks.”
