In an effort to settle the debate once and for all, Dr. Derek Muller from Veritasium and Destin Sandlin from Smarter Every Day have executed a well planned out scientific demonstration to finally clear up the truth about toilet swirl.
And yet another amazing experiment with resonance. A sheet of metal and some salt grains then just add vibration.
This is an excellent video showing the effects or resonance. Great for physics students.
It’s always been the case that our kids want to help out with the cooking and recently Alex has been wanting to help chop up anything. This leaves us with the dilemma of letting him loose with a sharp knife and having to watch him like a hawk, thus preventing you from doing anything else OR say “No Way Jose” and loose his interest and keenness to be involved.
Take a look at it in action in the photos below so you can see how they work and if you want to know more follow this link to take a look at in in the fiveotherwise Cook shop.
Many people say that you should never give a child a sharp knife, if that’s the case then when do they learn how to use on properly and safely? The key to teaching them knife skills is, as always, carefully supervised use of the proper tool. Show the child how to use the knife and guide their hands when they are first learning. Make sure they keep their fingers out of the way of the blade as it cuts, the finger ring and guard help with that. Never allow them to run their fingers over the blade or put the blade on anything that they are not trying to chop up. Always ensure the knife is used on an appropriate cutting surface and that the knife never leaves the surface and never goes near faces. You know your child’s ability better than anyone, so only proceed if your are sure; their safety is your responsibility. Also, it’s probably worth starting with the peeler as this is easier to use, and then you can demonstrate chopping whilst working together on a meal.
This weekend we tried out a rather good recipe for a frittata that we’ve wanted to try for while, it’s a bit like the one at www.food.com. The recipe first requires you to fry the potato, leek and onion on the hob before adding the spinach, whisked egg and then putting the cheese topped dish into the oven to cook. It needs the ingredients to be cooked together in the same pan that then goes in the oven for 10 mins. You can use a frying pan with an oven proof handle but for feeding six this gets quite big. So using Tart Tatin, which is designed to go from hob to oven, is really neat. The layering made it a rather attractive lunch. See what you think.
