Expanding foam and science experiments.

The Red Green show makes a big thing about 'the handyman's secret weapon - duct tape'. Well now there is a runner up. The number two secret weapon of the handyman is.....expanding foam!

Usually there is two ways expanding foam works. It either comes out really fast and runs out before you get all of the holes filled or it comes out really slow and keeps on coming forever. You fill every hole in every house on the block and it just keeps on coming. Well recently I went to fill holes in my brothers basement and I had a third thing happen. I could not get it to start so I pushed on the nozzle so hard that it broke off. Fred said I should hit it hard and see what happens, so I hit it on a rock and it started working. The problem is that it would not stop either. So I tired to use it anyway but without the nozzle it was hard to get the foam into the holes. The results are pictured below I think more went on the ground than on the foundation. This sounds like good material for another Red green show spoof like the one I already have on YouTube under bobdavis321.

We all have a favorite science experiment we like to perform. It is called leave a cup of something sitting around and see what happens. There are three possible solutions. One is It gets consumed by the cat. Two is It gets spilled on the floor. The third is the most fun - Something grows on it. Now the best material for this kind of science experiment is coffee. We all know that the nuclear resonance of coffee is slightly elevated by the caffeine so things grow in it in hyper mode. The results can be just amazing as seen in the picture below!

Another science experiment is called the bread drawer. Yesterday I cleaned it out and found some really nice looking green bread. I am sure the added color makes the flavor interesting as well.

Far, far better than coffee is drinking chocolate.

These "Leaving things in a mug" experiments have been a school, then office special hobby of mine for 30 years.

When someone goes on holiday for 2 weeks, put their mug on their desk and put in at least 4" of tea of coffee for them to have when they return.

The fastest, furriest and most colourful results come from drinking chocolate.
