the one that always used to cause me mental stress regarding the downward spiral of humanity was the 3 litre milk container...produced in the 10's of millions....with one small problem...the 1st time you used it milk went straight onto the bench, floor or you unless you were turning it upside down into a pot
They had instructions on the side.
1. remove lid.
2. person A should hold the handle while person B holds the underside with both hands.
3. person A aligns an upside down glass with the top of the container.
4. working in unison, the container should be briskly turned downwards while keeping the glass aligned with the top
5. two enormous glugs of milk will fill most glasses. STOP pouring after two glugs.
we have those green safety fences here too except there called gum trees
Gums trees would almost be safer... and at least they wouldn't dismember me.
