ELI5: How come sticky things (like spilled coke) can stay sticky for days or weeks? Shouldn't they dry up relatively quickly and lose their "stickiness"?

No. They will stay sticky from their sugar content. When things dry up it’s because the water in them has evaporated, but when something sweet spills the water evaporates and leaves the sticky, sugary mess behind. Hope that helps!
