Halp pl0x?

I need to think of something to make in resistant materials (which hasn't been already made or is an item but has been made better somehow)

I have these themes to choose from:
Celebrations
Travel
Blast from the past
Sport
Lighting
Educational toy
Outdoors
Display
Sortage
Sestain ability

Yeah im uncreative.

So you have to invent a new item that somehow relates to one of those themes?

Asking for help in general section on mpgh....
