Glow King75pc UV Blacklight Reactive Fluorescent Neon Balloons for Tying Balloon Animals / Decorating (PUMP NOT INCLUDED)

Please advise if these ballooon need a special light reflection to react and glow ? Or just when it is dark they glow?

Having a hard time getting pump to blow them up. using small nozzle and still not working. please advise. maybe a video??? they do glow well!

Will a normal hand pump work? What are you using?

Can you blow up these balloons 8-10 inches long? Making a neon sprinkle backdrop for an 80s party.
