Brainstorming Idea Three: "Invent a Time Machine That Only Works on Tuesdays"

Objective: Create a time machine that only operates during the sacred day of Tuesdays. No weekends, no Mondays, no birthdays, no holidays. Just Tuesdays. The rest of the time, it's a glorified paperweight.

Key features:

• Only works on Tuesdays. Don't bother trying on any other day of the week, you'll just get a sad, blank screen with a hint of disappointment.
• Can transport users 10 years forward or 3 years back, but not simultaneously.
• Comes with a built-in "Tuesday-ifier" which will convert any non-Tuesday outfit into a suitable Tuesday ensemble.

Target audience: Anyone who loves Tuesdays and hates mornings.
