INFLATING BALLOONS WITHOUT HELIUM!

Usually helium is used to float balloons, but this is a job that must hire and you will be expensive.

You can achieve the same effect at home with the following ingredients:

• Approximately 500 gr sodium bicarbonate
• 500 ml of white vinegar
• A bottle as soda, preferably 1 to 2 liters.
• A funnel to put the ingredients in the bottle
• Your favorite balloons

Fill your bottle halfway with white vinegar, then put baking soda to one half the globe (you could help with a needleless syringe), then connects the input of the globe with the mouth of the bottle without baking is out, now is the time to hold the balloon in the mouth of the bottle and let fall baking up white vinegar, chemical reaction generated inflate your balloon as if by magic.
