How to make a flying ball
A flying balloon is a good match for any holiday event. Usually, purchased flying balloons are filled with light volatile gas such as helium. At home, to get such gas without special equipment is almost impossible. But helium is not the only gas that can be used for such purposes. At home, without extra work, you can get hydrogen, which is also suitable. But here it’s worth considering that hydrogen is extremely explosive, so it’s undesirable to make more than one balloon. And in general, the whole experiment should be carried out outside the domain and in the open air.
We got 7 grams, you can take more foil, the reaction will be faster and there will be more hydrogen.We also take a tool for cleaning pipes (TITAN or MOLE) in pellets, 19 grams is enough for us. Be careful of this caustic substance, wear rubber gloves. Wash your hands with plenty of water.Next, take a plastic bottle filling it with one third with water, and drop it into a bucket with cold water. For convenience, we take a funnel and pour our aluminum chips and pipe cleaner into the bottle, then quickly put the ball on the neck of the bottle so as not to release the hydrogen. It is better to isolate the bottle neck with tape.The reaction begins, the balloon inflates completely after about 15-20 minutes, the plastic bottle is heated and so that it does not melt due to overheating, it dips into a bucket of cold water.As a result of the reaction of aluminum,Sodium hydroxide and water forms Sodium tetrahydroxoaluminate and hydrogen, which inflates our balloon.When the ball is pumped, squeeze the bottle so that some of the hydrogen from the bottle goes into the ball, twist the tail stronger and remove the electrical tape, then remove the ball from the neck.We wash the tail with water, if our ball is not fully inflated, you can blow it up a little like an ordinary ball.We ask someone to hold the ball and firmly tie the tail.The ball flies very well and will delight you and your children. In order for the ball not to be blown away in half a day, use gel for flying balls, for example, “hi float”.
It will be necessaryFor the experiment we will need:
- - aluminum foil,
- - a tool for cleaning pipes (Titanium, Mole) - Caution! Alkali!
- - plastic bottle,
- - bucket with water,
- - rubber ball,
- - funnel,
- - water,
- - etc.
Making a flying balloon with your own handsWhen conducting an experiment, be sure to use rubber gloves and special glasses to protect your eyes! First of all, roll the kitchen foil into small strips and cut into small pieces.And we collect in a small plastic cup.
ConclusionAt the end of the experience I would like to add that such a ball will descend to the ground after about 6-12 hours of flight. To increase this time, you can use a special gel,which is sprinkled in specialized stores selling such balls. Be careful: a pipe cleaning agent (Titanium, Mole) is used to make a ball - it is caustic alkali, be extremely careful! Also inflated do not bring the ball close to the fire. Otherwise, the hydrogen in the balloon will bang out with a loud pop.
