Dry Ice In Water

Observing The Reaction Of Dry Ice In Water

I always wanted to try this (put dry ice in water) and last year I got the opportunity. When I bought some meat from Donald Russell it was delivered packed in dry ice (frozen CO2) i.e. solid carbon dioxide. This dry ice was used to keep the meat cool in transit. The meat and dry ice are transported in a polystyrene box which provides lots of insulation. However the heat does percolate a package like this and the dry ice sublimates, but usually there is some left on arrival. If not the meat temperature may rise too high. So I had a source of dry ice.

The first thing I wanted to do as soon as the meat was stored in a cool place was put the dry ice in water and watch it bubble away and the vapour flow out and down the side of the container. I caught it on video below:

Teapot Cleaning Methods

Should you practice teapot cleaning or not?

Some people think teapot cleaning is unnecessary and that it spoils the flavour of the tea. If they have traditional brown earthenware teapots they probably don’t see all the tannin stains on the inside. With a stainless steel teapot you see them all and they start to form very quickly from new, or after cleaning. Tannin makes a teapot look disgusting. Not something you want guests to see when you make them a cuppa, or when they make one for you.

Teapot cleaning can be avoided by keeping it clean. One way is to make sure it’s emptied and rinsed out immediately after use. Letting it stand with old tea in it until the next mash allows the tannin deposits to grow. Continue reading “Teapot Cleaning Methods”

How To Open A Wine Bottle Without A Corkscrew

This Is How To Open A Wine Bottle Without A Corkscrew

It would appear to be a very simple process to open a wine bottle without a corkscrew. Just look at this video to learn how:

If you aren’t happy with that method try this one. There probably aren’t many corkscrews where this chap comes from:

Of course the British way is the simplest. Only buy wine bottles with screw caps and just unscrew them.

Another Method Of Opening Food Cans

Introduction

The video here demonstrates another method of opening food cans without a traditional can opener.

This Is Another Method Of Opening Food Cans

This is another method for opening food cans without a can opener. It involves grinding off the folded over edge of the can. The grinding material is in this case is flat concrete laid on the ground. I must warn you it does get a bit messy when the can begins to open:

Heating May Make Us Fat!

The title ‘Heating May Make Us Fat’ has no spelling mistake.

Check out this article at the BBC where Dutch researchers at the Maastricht University Medical Centre recommend heating homes to no more than 19°C (66°F) because:

Heating May Make Us Fat.

Below that temperature (19°C) they say our bodies continue to burn calories to keep us warm.

Interestingly the same article suggests, further on, that heating above 23°C (73°F) also causes us to burn calories by sweating to keep cool.

Spilling Juice From Cartons or ‘Tetra Paks®’

Introduction

This post contains instructions on how to avoid spilling juice from cartons or Tetra Paks®, with a rectangular cross-section, while opening or lifting them. It’s quite natural to grip cartons by the easiest method (the broad sides) while opening them, or lifting them when they’re still full, causing the contents to pour or squirt out inadvertently. Cartons with a square cross section are indifferent to the sides that are gripped when lifting or pouring.

Situation

You go to the refrigerator and take out a new cool carton of juice. You hold it firmly and take off the seal and juice spurts out at you and runs down the side of the carton, or you pick it up after removing the seal and juice pours out as you grip it. Before you’ve got it in a glass you’re in a mess. This is usually caused by the way you grip the carton. Continue reading “Spilling Juice From Cartons or ‘Tetra Paks®’”

Clearing Snow From Your Car

The scenario when you begin clearing snow from your car:

You just got up to go to work and your car has 50mm of snow all over it. You get your warm clothes on and rush outside to begin clearing snow from your car. What do you use?

  • Hands. “Oh! That’s so cold.”
  • Hands with gloves on. “Oh! They’re so wet and cold – the gloves are ruined and I still haven’t moved much snow.”
  • A piece of cardboard. “Oh! The snow has melted and soaked into it and now it’s disintegrating.”
  • A Soft-bristled Hand Brush. “Oh! That’s great. It’s moving large amounts of snow very easily and is resistant to the wet. The bristles are so soft they aren’t damaging my car’s paintwork. I’ll soon have it all swept off and my hands are staying relatively warm and dry.”

Soft-bristled Hand Brushes – Available from hardware stores. Example.

Don’t forget to carry one with you.

NOTE: Some hand brushes are sold as ‘Banister Brushes’. Some may have soft bristles but others have stiff bristles. A soft flexible bristle is required to prevent the paintwork getting scratched.

I’ve Spilt Paint On My Patio Slabs. What Will I Do?

Introduction

“Oh dear! The spilt paint on my patio slabs created a 20cm dia. puddle when my tin of mahogany paint blew over. It was tipped up by a gust of wind which lifted the cardboard it was resting on.”

“There would have been photos but I had to swear first and then get on with cleaning it up.” — HC

Euro Banknote Issuing Country Codes

Introduction

The Euro crisis has caused some people to be concerned as to who is the Euro Banknote Issuing Country for the banknotes that they hold. The concept being that if a country in the Euro-zone goes belly up its notes will lose considerable value while the notes of the other Euro-zone countries will maintain their value. This situation is encouraging some people to hold onto the notes issued in certain countries while ditching (spending quickly or returning them to the bank) notes from certain other countries.

Table of Euro Banknote Issuing Country Codes

So according to Wikipedia this table relates the serial number prefix on Euro Banknotes to the country that issued them (see the notes below where codes are in parenthesis):

Euro Banknote Issuing Country

NOTES:

There aren’t any notes prefixed with the letters in the notes below.

  1. W, K and J are reserved for countries that are not yet in the Euro-zone.
  2. R is reserved for a state that doesn’t currently issue Euro Notes but is in the Euro-zone.

EXAMPLES:

  1. The following example is a 5 EURO note from The Netherlands: P22280693815.
  2. The following example is a 10 EURO note from Germany: X73209895409.

Durham Cathedral Bungee Jumping

Introduction

It was the second day of our vist to the Durham area. It was a damp morning with missle in the air but we enjoyed our walk along the Wear river bank opposite the castle and cathedral. We crossed the Wear and went to the cathedral where the vaulted ceiling amazed us. Apparently it is the forerunner of its type with ceiling ribs in the shape of pointed arches. How surprising, in this type of location, to find Durham Cathedral bungee jumping in progress.

When we went outside, on the Cathedral green, and found bungee jumping taking place with someone being winched up ready to jump.
