Honda Global | Honda R&D Co., Ltd., a research and development subsidiary of Honda Motor Co., Ltd., today conducted a launch and landing test of an experimental reusable rocket*1 (6.3 m in length, 85 cm in diameter, 900 kg dry weight/1,312 kg wet weight) developed independently by Honda. The test was completed successfully, the first time Honda landed a rocket after reaching an altitude of nearly 300 meters.
How does Helium fit through places that Hydrogen can’t even though its bigger? Is it because Hydrogen would react with things along the way while Helium won’t?

I suspect it’s because the hydrogen molecules are bigger than a single helium atom, which doesn’t form molecules (since it’s a noble gas).
So the hydrogen molecule only seeps through if it’s oriented right (since the hydrogen molecule is a stick-shaped molecule).
I’m also curious, I thought hydrogen was the worst in this regard.
I like your theory on hydrogen reacting as it moves through materials.
