What would make you stop at a booth?

Trade show visitors walk past hundreds of booths. How do we trigger genuine curiosity so they actually stop and ask what we do?

So I’d love your creative input:

• What kinds of interactive elements work best for B2B audiences at tech fairs?
• What kind of story or visual instantly grabs attention (without being just another buzzword)?
• Have you seen or done something clever at a trade fair that really stuck with you?

Any ideas, examples, or even crazy concepts are welcome, thankss!
