If this really works, it's great for #geocachers as a bunch of butterfingered "heavy drinkers" ..

At least two thirds of the new #geocache containers in Finland today are PET-plastic bottle preform tubes with standard size plastic lid caps (approx. 6000 p.a.)

.. but naturally this new improvement doesn't work against squirrels and other sharp-toothed rodents 🐿 🐀
