Eggs are kind of weird. All that see-through goop with the yellow blob in it — eww! But when we cook, eggs turn into all kinds of tasty foods. We scramble them, fry them, and bake them into cookies and cakes. Well, in this video sent by our fan William O., a chef shows off some amazing egg tricks, and a few use math. Did you know that fresh eggs sink underwater, but bad eggs float? Or that the angle at which fresh eggs tilt underwater tells you how many days fresh they are? Then he shows how to fry eggs inside onion rings, tie-dye them, and other wacky snacks. Pretty eggsciting!
Wee ones: Eggs are round. Find 3 round things in your room, and if you can move them, line them up in size order from smallest to biggest!
Little kids: If you’ve cooked your 4th, 5th and 6th tie-dyed eggs, what 3 numbers come next? Bonus: If you put 9 raw eggs in water, and the number that float is 1 more than the number that sink, how many float?
Big kids: If you’re cooking eggs inside onion rings and squiggly pepper rings, and every 3rd one starting with the 1st egg is inside an onion, what veggie does the 21st egg use? Think carefully! Bonus: Out of your first 30 veggie eggs, how many are inside onions?
The sky’s the limit: If you make 100 fried eggs for breakfast, and there are twice as many green eggs as plain eggs and 7 times as many purple as plain, how many of each color do you make? (Hint if needed: for each plain egg, how many colored eggs are with it in a “set”?)
Wee ones: Items might include toy balls, marbles, clocks, or the bottom of a lamp shade.
Little kids: 7, 8 and 9. Bonus: 5 eggs float, and 4 eggs sink. If the floating number were equal to the sinkers, you’d have 1 less egg in total (8) and the floaters would be exactly half.
Big kids: It uses pepper. The 3rd egg uses pepper, and 21 is a multiple of 3 also. Bonus: 10 eggs. We’d have to cook 31 to sneak in 1 more onion ring.
The sky’s the limit: 70 purple eggs, 20 green and 10 plain. Each plain eggs has 2 green “friends” and 7 purple “friends,” making a set of 10. Within 100, you’ll have 10 of those sets.
