Doing it the hard way!

At lunchtime we had a debate as Costco have an offer on compost (3 120L bags for the price of 2).  How much does that weigh?  Are they really 120L each of is it 3 40L bags. 

I did a google and it said 25L weighed 4kg.

Well Dad had some 75L bags in the garage and so they needed to be weighed.  First he weighed himself and then the bag plus him!  Roughly 20kg.

Why don’t you just weigh the bag I asked?  (I had to let him go through the process for a Silly Saturday Blip) and sure enough it weighed 20kg!

Thanks to Dad again for his fun and silliness!
