In a transparent plexi tube, which you showed empty before, you put three silk scarves well separately.
Show both ends of the tube to the audience again, then you bring it to your mouth.
Like an experienced trumpet player, you blow forcefully into one of the extremities.
The scarves emerge from the tube.
Capture them and show that, enigmatically, they are all three attached to each other this time.
A surprising effect, you can then use these scarves for your next turns.
Another effect that doesn't require too much agility.
