Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Edited from to 1/4th normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

Broccoli, Ground Turkey and Cheese QuicheAfter many years of cooking, a cook always has some simple, homemade quick meal ideas for fast nights! Link to Recipe: https://www.chrisdoeswhat.com/easy-dinner-quiche/ One of those is my own creation of Quiche, Yummy! Of course, I have several creations but this is my fast, easy and delicious dinner Quiche! Great thing is, this tastes good hot or cold! If you happen to have any left (we never do) then take it for lunch the next day!I make a very large portion for my family and this recipe would probably feed 6-8 people! My 2 boys and Hubby will devour this! If you wanted to make a smaller portion, I usually half a recipe and this recipe would be easy to that too.
