this is good. it shows you where apollo missions 11 to 17 landed (13 never made it). amazing that the landings were all so close to each other! google moon. you can also zoom in on each landing site and look at other sections of the moon. fascinating facts and figures.
you’d probably be surprised to hear that there are loads of science references in numerous episodes of the simpsons, from homer’s time travelling toaster to principal skinner’s riposte on a visit to a private school, ‘hmmpf! due to school board cutbacks OUR periodic chart only has 15 elements….and they’re all lanthanides!” there are plenty more here including my favourite…see if you can spot it.
make your own ginger beer! it’s much better than shop bought rubbish and only contains natural ingredients. plus you also learn how fermentation works. here’s the recipe:
add one cup of sugar to a clean 2 two litre plastic pop bottle. finely grate about 2 tablespoons of root ginger and add this to the bottle. juice a lemon and add that. now add about 1/4 teaspoon of baking yeast. fill to about three quarters with cold water. shake until the sugar is dissolved then top up with water to about 4cm from the top and screw the lid on as tight as you can. leave in a warm place (about 30-35°C) for 24 hours. DANGER! any longer and you run the risk of an explosion so BE CAREFUL!! the bottle goes rock hard when it’s done. put the bottle in the fridge for about 4 hours to stop the reaction, then very carefully release the pressure. sieve off the bits of ginger and drink. (it is alcoholic but only just, about 0.2 to 0.4%). mmmmm! nice!
