THEATRE TEACHERS - I NEED YOUR BRAINPOWER!

I'm on the hunt for the perfect 15-minute play to use in a hands-on technical theatre summer workshop, and I want YOUR best recommendations.
Here's the goal:
I need a short play that's a goldmine for teaching ALL the elements of technical theatre - lights, sound, set, props, costumes, maybe even some fun effects or creative staging opportunities.
What I'm looking for:
• 15 minutes or so in length
• High school-friendly (and actually engaging!)
• Something students would enjoy reading, not just tolerate
• Strong potential for creative design choices
• Clear moments for cues, transitions, and storytelling through tech
Thanks for your suggestions and responses.
