Mirror trick - twenty eight years ago the evil queen casts a curse and takes everyone to a land without magic. On Emma's birthday she makes a wish, meets her son eight years later, takes him back home to Regina mills. @starsthatburn [ credit for the gif set]

Mirror trick 🌌

[operafantomet]

How did the "Christine-shaped-hole" in the dressing room mirror work in the Las Vegas production? Was it just the hole that opened for Christine to walk through rather than the entire mirror plate sliding out of the way? Or was the hole there for the entire scene? Thanks!

The mirror was solid for most of the scene, only at the end of the mirror scene did they open what looks like her silhouette so she could walk through that. And then the mirror returned to normal. Pretty much like the original mirror scene.

It would have been the most brilliant mirror trick, had they not insisted on drowning the dressing room in mist Every. Single Time. The audience ended up just seeing a foggy cloud with a staircase.

Mirror Trick

This is a technique I came up with while looking at a table of squares. (DISCLAIMER: I am not the first or the last person to discover this.)

If you have all of the squares from 0-25 memorized, then you can quite easily find the squares from 26-50 as well. All you have to do is find the mirror over 25 of the number being squared and add 100 times the number’s distance from 25.

Mathwise:

N=an integer from 26 to 50 M=50-N (aka, the mirror of N across 25) n=N-25=25-M (aka, the distance from N and M to 25)

N²=M²+100n

Why?

This can be shown by using difference of squares:

N²-M²=(N+M)(N-M) N²-M²=50(2n) N²=M²+100n

The same idea can be used for mirroring across 50:

N=an integer from 51-100 M=100-N (aka, the mirror of N across 50) n=N-50=50-M

N²=M²+200n OR ALTERNATIVELY: N²=M²+100(N-M)

Example:

To find 38², first note that its mirror across 25 is 12, and it is 13 away from 25. 12² is 144, add 1300 for its distance from 25, and voila! 38²=1444

I hope you enjoy this trick, it has helped me a lot while trying to square numbers fast! :)
