Amy and Nick are preparing for the Halloween party, and they need spooky sounds ,so they prepare a bunch of balloons and hex nuts.First ,they place hex nut inside the balloon and blow it up.Then,they spin the balloon until they get the hex nut moving.The flat edges of the hex nut rub against the inside of the balloon , so it causes vibration.The reason of the spooky sounds is the vibration .

Amy and Nick are preparing for the Halloween party. There is one thing they don't prepare.They can do some spooky sound effects for the party.Nick has instructions on how create spooky sounds with balloons. They need a bunch of balloons and hex nuts. First, put the hex nut inside the balloons. Second, blow up the balloon. Third, tie a knot. Next, spin the balloons. And you can hear the terrifying sound.
The flat edges of the hex nut rub against the inside of the balloon, thus causing it to vibrate. This vibration creates the spooky sound. Barely would we hear a sound if we used something with a smooth surface like a coin or a marble. It's friction that causes the effect.This is the fun and power of experiments. Not only does it amaze us, but it also teaches us about different scientific phenomena.

Amy and Nick are prepare for the Halloween party. They want do some spooky sound effect for the party. And they do the experiment to discuss what make the balloon vibrate.

Amy and Nick are preparing for the party. And they want to do some spooky sound effects for the party. All they need to prepare is a bunch of balloons and hex nuts. And they finally make the sound and plan to make the party more spooky. And Amy wonder why they can only use the hex nuts to make the sound. Nick explain to her. Because the flat edges of the hex nut rub against the inside of the balloon; this causing vibration that makes spooky sound. Barely would we hear a sound if we used something like a coin or a marble, because they are too smoothly to cause the vibration. They also learn the power and fun of experiments. And they plan to do more interesting next time.

Amy and Nick were preparing for the Halloween party. To make spooky sound, they thought  a fantastic idea. By using a bunch of balloons and hex nuts, they created the weirdest sound. It was friction that caused the effect. Amy was amazed at this scientific phenomenon. She hoped  that they could do some interesting experiments next time.

Amy and Nick are preparing for the Halloween party. They prepare almost everything for it. And Nick suggests that they do some spooky sound effects. So they use some hex nuts and balloons to make it. Then, Nick explain the principle of it to Amy.

Amy and Nick preparing for the Halloween party. And they need to make some spooky sound. Nick told Amy how to use balloon and hex nut to make the spooky sound. After that, they also try to use coins to make the spooky sound but it didn’t work. It hardly to use something with a smooth surface to make a sound.

Amy and Nick are preparing for the Halloween party.Nick wants to make some spooky sound. First they put the hex nuts in the balloon and blown it up. Then tie a knot and spin the balloon.The edges of the hex nuts causing it to vibrate and the vibrate cause spook sound. We can not use coin or something else with amooth surface because it's friction that causes the effect.

Amy and Nick were preparing for the Halloween party. Nick thought they can do some spooky sound effect going with their party’ s theme.To make the vibration which caused the sound, they put the hex nut into the ballon at first. Second, the balloon was blown up tied a knot. Third, they spin the balloon until the hex nut moving. After they finished it, Nick suggested that they could try a different number of hex nuts or various sizes of balloons to see if the sound changed. Then, Nick explained the vibration resulting from the hex nut rubbing against the inside of the balloon, and we could barely hear the sound if we changed the hex nut into something with a smooth surface.
