Sometimes you need a big funnel – why not cutting the top of a plastic bottle and use this?
I find this instruction great again: with little means reaching something practical and additionally recycling :)
By the way you can use those funnels, too, when pouring little beads from one container to the other, I don’t like to use my kitchen funnels for this.
Incidentally you can use up the rest of your bottle, too ;-)
