ADVICE OF THE DAY
December 24, 2020It works best with cold water.
December 22, 2020In the "floating" condition, the angle of the cork is not important, but only whether it partially protrudes from the water.
December 18, 2020Today's question is about drops on the window pane that you can see without a magnifying glass. Please make sure that your "garden" looks similar to Mr. Santa's.
December 17, 2020The eye of the observer is set as the first fixed point, the listed objects then follow. The four objects do not have to be positioned exactly in a line, but can be moved a little to the right or left if necessary. The options A and C or B and D are therefore not identical.
December 16, 2020The original flame is counted as well. The experiment is easier to carry out in a dark room.
December 13, 2020Today's question is about the coloured head of the needle that is under the cardboard disc.
December 12, 2020Please make sure that you use sparkling water "classic" with a lot of carbonic acid. By the way, the wooden stick is only used to start the sultana from the very bottom, the sultana is not impaled. So you can also use a pen. It might be easier with a small, dry sultana.
December 9, 2020The top domino is also counted.
December 6, 2020The funnel should be aligned with its axis of symmetry exactly to the candle flame, as shown in the film. The middle jet of the air stream hits the candle flame differently than air from the edge of the funnel.
December 3, 2020Please make sure that you slowly but completely pull one end of the earpiece out of the toilet paper tube. If there are several minima in the volume of the sound, please mark them all and then measure the distance between them. By the way, the app is called "PhyPhox".
