While all balloons can be filled with helium, not all balloons will float. 16-inch foil letter and number balloons can only be filled with air as they are not designed to float.
This is because the foil's size is too small to float and the helium volume pumped into it is not enough to lift the weight of the material the balloon is made of. The wonders of science.
