How to Make Balloons Float without Using Helium


We are quite familiar with floating balloons, which uses helium gas as the primary fuel. But sometimes, it gets challenging to manage helium gas. The cost of helium gas is also high, so when you are in dire need of a floating balloon, then helium gas can be a problematic gas to obtain. So we have to find some alternative for helium gas.

Besides, helium gas can sometimes be harmful to the health of the persons who come in direct exposure. Inhaling pure helium can even cause death to certain people. For this reason, today, we will discuss a technique that will include hydrogen gas instead of helium as the primary fuel for the floating balloon. So without further adieu, let us jump into the method.

Required Materials

The first aspect of starting any process is gathering the necessary materials to help you run the operation. For making a hydrogen-based floating balloon, we need to have the materials for producing hydrogen. You will need two big bottles, and it is better to use bottles with two volumes worth two liters. You will need a drill machine for drilling holes in the bottles. You will need sodium hydroxide, which is commonly termed as caustic soda in the market.

Required Materials

You will also need a funnel to pour water. The process requires strong adhesive for a firm attachment. For this, you can use a glue gun. Besides, you will need aluminum foil paper. This is a common household material. You will need a plastic pipe, and finally, you will need some colorful balloons. After you have gathered all these materials, you can start the process.


You have to start with the drilling machine. We have already mentioned that you will need two bottles. So you have to empty the bottles, and then you have to use the drill machine and make two holes. The first hole will be on the bottle’s upper side, and the other spot will be on the bottle’s cap.

Now you have to take a plastic pipe, and then you have to cut the line with a cutter. You have to measure a safe distance between the two bottles, and it should not be more than one foot. You have to insert the pipe through the holes, and then you have to use a glue gun to seal the holes. In this way, there will be no possibility of air intake or outturn.

After you have sealed the pipe with glue, you have to take the aluminum foil, and then you have to cut them into small pieces and make small balls. You have to put the aluminum balls inside a bottle and then put some caustic soda in it. Then you have to close the lid, and on another bottle, you have to pour some water using a funnel.

After the reaction starts inside the bottle with caustic soda, you will observe gases coming out of the other bottle as bubbles. These bubbles are hydrogen. Now you can put a balloon attached to the bottles’ mouth, and then you will see the gas filling the balloon. In this manner, the balloon will start to float with the help of hydrogen gas.
