Maltese Bread pudding as an Analogy for the kidney nephron

Maltese Bread Pudding           
                
  1. Soak the bread, in water for about an hour until soft. ( cut loaf in half).
  2. Pre heat oven to 200C and grease a rectangular baking dish measuring about 30cmx 20cm.
  3. grab the loaf with your hand and squeeze out excess water. You can put the bread in a clean tea towel and squeeze.
  4. Mush up the soggy bread with your hands and add the other ingredients except the dried fruit and mix well.
  5. Add the dried fruit .
  6. Spread in the baking dish and flaten surface with a spatula.
  7. Bake for about an hour, until it feels firm .
  8. serve warm or at room temperature ( or in summer, cold from the from fridge with some custard)
I am using the above recipe to help my Year 12 biology class understand how the kidney's nephron works. I needed the photos for the powerpoint, which I will link here.

fixing a broken zip with a broken slider

 Rather than unpicking and replacing a zip to fix a broken zip slider, it is much easier to take off just the slider, when your zip has all the teeth and works perfectly well  but  looks like this:

The first thing to do is remove the old zip slider off the jacket. You can gently widen the zip with a flat head screw driver to let it slide off the metal end, shown here, or take off the metal end itself. Be careful not to damage the teeth and keep the metal end.
 Then slide the old slider off . Remove a slider of a matching zip. ( You can just cut off the ends as I did because its not longer needed) Make sure the teeth and slider are exactly the same size, and colour match or use a contrast colour that works. You don't have to worry about the length of the zip, and if you are able to buy a zip head by itself or cannabis a another item do that. Alternatively, you might have to buy a matching zip, so go for the smallest size.

Once you have your zip head, slide the zip over the end of the zip where you removed the metal end, or slightly widen the new zip slider with a flat head screw driver to get it over the metal end.
Either way, make sure to put the zip faces the right way and with the wider end of the slider to the top of the jacket. Look at another zip if you are not sure.

Once you have the zip slider on, test it a few times then you are nearly there.  If you have widened the zip slider, gently return it to the original size with a pair of pliers, or use the pliers to return the metal end. Make sure that the zip can't come off that end even when the zip is just sliding on that side alone.

If the zip slides off, add another clip, use pliers to make the metal end fatter or even add stiches of a matching colour so the zip can't fall off.
If you ever have a zip slider that keeps sliding off, you can see its easy to fix.

By the way, if a zip slider won't close the teeth together you can try using pliers to close the slider gap slightly, as it might not be pressing the teeth together enough.

There you go- all fixed!
