Here’s what I did with an empty plastic bottle last night. I had an open can of dog food that I wanted to put in the fridge but I didn’t want it tainting anything else – like cheese!
I peeled the label off the bottle and cut it in half with the kitchen scissors. Then I covered the can of dog food with some greaseproof paper and inverted the lower half over the paper and rammed it down. It works fine, though a straight sided bottle would probably have worked better.
I am using the other half – with the neck of the bottle – as a handy funnel for filling recycled jars with dried beans, rice or whatever without spilling it everywhere. You can see it propped in the glass.
I have also heard you can put potting soil in the lower half and grew little plants there, like a terrarium. I intend to use plastic bottles – well, the bottom half anyway – to place over seedlings to protect them from frost.
