Helium is a scarce and irreplaceable gas essential for medical and other technologies. Future generations will condemn us for wasting it on this kind of trivial nonsense.
Hydrogen is way too combustible. It could ignite merely by your body’s static charge. In retrospect, you drop a burning matchstick inside a chamber of helium and nothing happens.
The mixture of hydrogen and oxygen is combustible. Pure hydrogen is not. Either way the amount of energy in the hydrogen to fill a balloon like this is too low to cause any amount of damage.
Pure hydrogen cannot combust, u just need to make sure that Oxygen stays away. Need an insulating and strong yet light material to keep the hydrogen isolated. The question is how long will it take to invent such wonder material
I also imagine if you put it in a flame retardent bag with no pressure instead of a baloon, there might not be an explosion. There are videos show a relatively weak explosion with hydrogen baloons indoors, but that is because they pop and mix with oxygen. A loose bag should be even slower.
