This is a very simple to build but fun puzzle, that you can make as a present or for yourself. ;-)

You will need a minimum of materials and only a few basic tools.

(Since English is a second language for me, please forgive me for the spelling mistakes I might make)

## Step 1: Materials

Because of the simplicity of this project you only need these few materials:

• a piece of string (at least 40cm)
• a small piece of wood (mine was about 10 x 5 x 0.8 cm)

## Step 2: Cutting the Wood

1. The first thing you'll have to do ist to mark the wood. Outline two pieces of about equal size. I made two identical parallelograms but you can be creative with your shape. They should have enough space on them to drill two holes each. (In my case the two holes had a distance of 3cm)
2. You should drill the holes now while the wood is still one piece since its easier to handle. The diameter of your holes should be twice as big as the diameter of your string.
3. After that, cut the wood along your marks.
4. If you want, you can get as fancy as you like with your finish but I would definetly recommend smoothing out the wood with sandpaper. You should also remove any pencil marks left on your pieces.

1. First you have to cut your string into two pieces of equal lenght.(In my case about 20 cm each)
2. Take one of the strings and tie one of your beads to one end. Then take one of the wood pieces and thread the loose end of your string through the first hole and back through the other hole. Then take a second bead and tie it to the loose end.
3. For the next step repeat 2. just make sure you thread the string through the loop created by your first piece before threading it back through the second hole. (look at picture 1 for reference)

And thats it, you finished your puzzle!

## Step 4: The Challenge

The challenge is to seperate the two wooden pieces, without cutting the string or removing the beads.

Have fun!!! :)

Look at the next step for the solution.

## Step 5: !SPOILER!-The Solution

1. Take one of the loops and thread it trough one oft the holes of the other woodpiece. (picture 1)
2. Once the end of the loop is on the other side of the wood you can pull the bead through the loop. (picture 2+3)
3. Now youre basically done. The only thing left to do is pulling the loop back through the hole. (picture 4)

Congratulations, you successfully seperated the two pieces!

<p>cool mate</p>
<p>wow</p>
<p>I used some extra 3D printed parts that I had around and built a version for my kids to solve. They are asking me to give them the solution. Not yet :)</p>
<p>A great puzzle. Loads of fun for family and friends that visist me.</p><p>As a matter of fact I altered it a bit and made a 3D drawing in 123D and printed it.</p><p>Thanks for the idea. </p><p>Luc</p>
<p>Your English is fine, but the pictures are great. Good job.</p>
<p>why would there english not be fine?!</p>
<p>The comment was made possibly because the author in the third sentence asks for forgiveness as to any spelling mistakes that may have been made as English is his second language.</p><p>Their.</p>
<p>Oh, I missed that. Thanks!</p>
<p>Awesome!</p>
<p>Wow! of course! So that's why the holes had to be twice the diameter of the strings! I was too lazy to work it out for myself. Thanks! Any others?</p>
<p>I shold have said &quot;three times&quot;...</p>
<p>I love these and they all work the same if they are this class, folded o.</p><p>thanks I may make a few for scouts!</p>
<p>I dont understand why I not positiv?I am very glad to see intresting things in this page.</p>
<p>I haven't made it yet, but I have collected many of the same type. There are 4 solutions to the puzzle, but they are all the same.</p><p>Thanks</p>
<p>That's nice!</p>
<p>This is a great puzzle and you explanation of how you made it is very good.<br>Best wishes, Rebou</p>
Nice. And your english is fine. <br><br>You almost provided a spoiler when you explained the size of the drill hole. <br><br>Thanks!
<p>just like old time grandfather trick good effort</p>
<p>Love it i may make one of these just for fun and get my friend to try it out and beat it</p>
<p>Fantastic puzzle! Love it. :)</p>
<p>This was one of my favorite puzzles.</p>
<p>Genius! i try it for my kids :)</p>
