Good show

Helium, nitrogen and dry ice (solid carbon dioxide) provide spectacular effects during performances and are invisible helpers for performing artists.

Gases can be considered as “secret stars” behind the actors in the footlights. Helium-filled balloons descend slowly on the concertgoers or ascend skyward in large numbers. Dry ice fog magically creates a mystical mood on stage or accompanies spectacular laser lightshow effects. But also at birthday parties, weddings or street festivals, gases – in this case, helium – are a welcome guest that make balloons into featherweight decorative objects.

And metal artists also turn to gases to help them create their works. This primarily involves welding gases, which help a give a column or a sculpture the desired shape.
