I don't understand why people are still talking about the bolt in the first picture. The bolt is NORMAL. The secret has already been exposed in the thread. Perhaps you need to hold it in your hand to understand how to drill the hole and instert the bolt. Oh, the wood is all ONE piece too.

The second pic same basic idea/method, just slightly modified.

Perhaps you would concisely explain the thing?

I will tell you the answer to that puzzle if you tell us the answer to the original posted puzzle. Smile

They are whole. Wooden puzzle makers can keep secrets too. But it is true that wood can be soaked, steamed and shaped. That much I do know.

I've been told by the maker of that puzzle

"The wood is not bent or twisted. Water is involved"

Not bent or twisted !!!!!?
It's getting crazier Smile
Then I guess the only (?) possibility left is that the wood is crushed....

Mehtas, the maker of first or second puzzle ?
Thanks for your help,

Nicolas,

I think it was the maker of first puzzle.

sometimes these makers give you trick statements to send you for a ride again. even though you've solved the problem. if that is the case then I don't see any point to go furthur on this puzzle.

I am kind of lost with this thing Smile
This week-end I have put a small piece of basswood (soft wood) in boiling water for 10 min. The piece was 3(long)x1(large)x1/2(thick) inch.
After this extreme treatment on wood, it will not bend more than 1/4 inch and then break! I did this with other pieces other size but it always breaks...

I begin to think it is not possible to bend small piece of wood like these!
I also remember an old trick where you can completely bend a cigarette in half (a side touching the other!), and the cigarette will not break if you roll it in bill. Maybe the same technique can be adapted, for example rolling the wood to bend into duck tape, preventing to break...

I remain kind of clue less Smile

Is it sensible to grow the tree around the bolt? Takes a while.

This is how I think it's done. Cut out the wood as is, then snap off one end, because it's broke (not sawn). There will be an invisible join. Drill the hole, insert bolt, and then reassemble with glue and no one is the wiser. mike

No!
belief is an interesting thing. truth is there, but people refuse to believe.

Good! you aren't supposed to! thus the amazing puzzle, the impossible object!

After showing my grandfather the arrow thru bottle impossible object and explaining how one is made, he then made several similar puzzles. his version was a wooden heart with a hole drilled in, then a wooden arrow is thru the hole. He personally did not care for basswood, it didn't work as well for him as another type of wood he used.

Any cabinet makers out there ??

Can a small bit of wood bend almost a 90 degree angle if it was steamed.

Look at the following picture again.

Why the section I've marked is bit moon shaped. why is the left side bit darker than the rest of the wood ??

Any clues ??

The Sponge, do you actually know how the "tooth and nail" was made ?
Are you sure there is no wood bending to make this object ?
The "arrow thru bottle" (or coin or..) is also an excellent impossible object !
Maybe same principle are involved like steaming or boiling wood...

Mehtas, I see you have also a lot of motivation for this puzzle Smile
I think for the picture you have showed, the right teeth CAN be bend on side, allowing the hole to be drilled and the bold to be inserted.
The wood can certainly not bend 90° or maybe it can but very hard (need expensive materiel), check this out :
http://www.compwood.dk/eng_presentation.htm

For the other tooth and nail, teeth are smaller making it much difficult to be bend (if not impossible)! The problem is that I can absolutely not think of another way...

Just a small historical info, Viking ship builder used to soak their board in a salt water for a day prior to attempting to bend them into shape...
Salt in water get bending wood easier...

You put the instructions for the bolt and the wood into your matter printer/builder and press the button. Today we have this working in wax, tabletop model takes instructions from a CAD program.

One thing about these impossible objects... they don't come with duplicate components. Almost the makings of a good trick if they did. Smile

Check out the 16th puzzle from the bottom of this page:
http://www.johnrausch.com/DesignCompetition/2005/entries.htm

It's called "Solitary Confinement."

If removing the screws is allowed, then there's no puzzle.
If removing the screws isn't allowed, then ????????

Note that some of the puzzles have solutions posted. This
one doesn't.

Yes, both of them.
I never said that, quite the opposite.


A puzzle is different than an impossible object. Different rules apply.

Instead of bending it vertically into a horse-shoe shape, how about bending it horizontally into sort of a denture-shape? You would only have to bend half as much. I guess you would only need to bend one end, so it'd be more of a L shape, except you don't have to go anywhere near 90-degrees.

It's difficult to describe, but I can visualize it in my mind.

Got it!

This is an illusion based on perspective, the bolt is actually diagonal in the pict., it's actually behind the post on the right, and in front of the one on the left. If you look closely at where the bolt enters and exits the two center posts, you'll notice that it's much closer on the left center post than at the right center post. The wood and posts are skewed to look square when viewed and shown from this angle.

Yes, it's hard to explain, but look at it closely, and you'll see what I'm talking about.

Props go out to my wife, who took one look at it and showed me how it was made/photographed.

The builder said water was used? Gotta love it, obviously, they like illusion and making people think just like Magicians do, and will use verbal misdirection just like ourselves.
