How does this work Mag?

YOU can see how it works in this video. It's not in English though.

Fun!

Sneaky!

It stills makes me seasick to watch.

Hi Geo,

As far as I can see:
- it's a 7x9 squares.
- with a diagonal cut through the squares (and 2 vertical at bottom), rearrange the bottom to make 10 rows first on 4th column (note going to his left) and then rearrange back to 9.
- he did this 3 times.
- Around 1:37 or so, he rearrange the squares back to 7x9 but the size is off by then because of the removal of the 3 squares. Not as tight. He didn't shake the tiles inside the wood box.
- Now with placing back the removed 3 tiles - they are rearranged at 7 rows on 4th column (note going to his right) and then back to 9 rows.
- when back to original size in the box with all the tiles back in - note that the tiles are tight inside the wood box and no dark spaces on the side.

- So the trick is to change the size of the cut squares by means of the geometric markings of the tiles and the vertical cut.

Maybe someone can give a better explanation.

Thanks Geo.

Well, my head is about to explode.....

Don't anyone show this to Knut Mueller.It might give him an idea.

mag,
To me,from the solution video,it looks like the tile was accounted for in thirds of a tile shown by the sliver shown. The video also made me hungry.

I'd rather just eat the chocolate bar and skip all the hassle.

Thank you Geo and MaG. I think I actually understand most of this, lol. I thought maybe the frame was switched, size wise but your explanation makes a lot of sense, MaG. Pretty neat!

I'm with Mad!

That was really cool.

I still think it's a 'slight of hand' magic trick. The guy seems to be palming the extra pieces and making them appear while the original configuration remains intact. Just my guess.

Actually it's all about the angles. You can see it explained in the video in the second link and in MaG's explanation.

Mind-boggling

I don't understand a word while he explains.... (neither in the first nor in the second video....)

All I could think of was a big Hershey chocolate bar. Now I'm going to go out and buy one.

Yup Ana, I watched both videos and still think there is no way to make the same size thingy fit into the frame without those 'extra' pieces. Nope. Not buying it. It's a trick.

I like what you said Marie!!!
