How to delete big items?

[Doesn't Fit]
How do I delete a shopping cart for example?
Now that I understand how to carry around super moneyballs, the shopping carts are just in the way.

[Doesn't Burn]
How do I delete the case the mortar came in?
I already fired the mortar, and the case never served a purpose.
So I want to get rid of it - it's huge.


For small items that don't burn (coins, trophies) you can stuff them in boxes and then burn the boxes. But I'm stumped on the big stuff.
