How to fill balloons without helium
Look at the Japanese trick to inflate balloons. You'll never use helium again!

Helium is the lightest gas, that's why it floats. But unfortunately it's very expensive and if you want to inflate a lot of balloons you'll need a lot of money. We'll teach you a way to save money by inflating balloons with other materials that have the same effect as helium and are much cheaper.
You'll need the following:
1 empty bottle of 2 liters (can be soft drink)
1 funnel
500 grams baking soda
500 milliliters white vinegar
Balloons of your choice
