Squeezing out every last drop

I try to squeeze out every last drop from bottles, tubes and cartons but they seem designed to make it difficult.  

Take toothpaste tubes for example.  I squeeze and roll, trying to coax the paste on to the brush.  None comes out but I will not be beaten - I just know it's not finished yet!

Just look how much is still in there! This one lasted for six more cleaning sessions.

The plastic tubes are easy to cut in two and then seal up again by poking one inside the other. 

Maybe it works out that I save the equivalent of one tube a year perhaps but that's most definitely worth the effort.
