This is really, really easy to do. (Note: you may be able to use this technique to grow other stuff in the form of a square ( actually in the form of a cube) and apply the general idea to other shapes.)

Step 1: Materials and Tools

You need 6, 8" square, 3/8" thick (or thicker) sheets of polycarbonate plastic. (Lexan)

You will need 4 gate hinges and 2 hinged clasps with flat head machine screws and hex nuts plus at least 8 or more 1" to 1-1/2" long, thin wood screws and possibly a 36" length of angle iron or aluminum angle (cut to 8" lengths to yield four pieces) if you have thinner polycarbonate, a power drill and hole saw, and a hand saw or power saw such as a jig saw.

<p>They look like minecraft fruit :)</p>
<p>Thought the same thing! xD</p>

I can see it now- instead of a watermelon, grow a pumpkin in a cube shape. Then, carve a Domo-Kun face on it. Voila! Domo-Kun Jack-O-Lantern.<br /> <br /> <br /> <sub><sub>I've got dibs on the 'ible. </sub></sub>
Do it!
Gotta wait until I have a garden to grow it in! Living on a boat and all, I don't have a very big yard :D
I'm on a boat Motherfu Ha ha very orginal I know I lived on a boat, the sail type for 2 years and build floating garden boxes out of blue foam board. I had a slip larger than my boat so I just attached them to the dock. Then I got a bigger boat and build two above ground planter boxes on the deck. I even tried to grow an orange tree, to combat the scurvy but I live in Alaska.
<p>OK, I know this is off-topic, but wow. That is an interesting life. xD</p>
<p>You just have to be imaginitive about where to grow. I have seen people grow things on walls and roofs. Doing this also cuts cooling and heating costs.</p>
you don't need a garden i grew a pumpkin in a large pot and trained the vine to a railing. when fruit formed i used pantyhose to support the weight.
you do, it's just REALLY flooded
So... rice?
salt water.......o_0
put it on the mast head. o_0
<p>Oh, they sell square watermelon seeds in Aliexpress ... ha ha ha</p>
<p>no way. this is crazy.I wish I liked watermelon</p>
<p>I saw a you tube from a russian show about the japanese square watermellon .. in that one the mellons were over a hundered bucks each , but were inedible and not good inside ( yellowish flesh) hy?</p>
<p>I saw this in a Japanese show and it was really nice. Great instructable</p>
<p>$80 for materials? Geez!</p>
<p>'This is really, really easy to do.' OMFG SO EASY</p>
I wonder if this could be doing to shape a pumpkin into a skull for witches hat?
I feel like this would introduce a ton of moisture-induced rot unless plenty of ventilation is drilled into each panel.
how do you deal with rain and condensation?
Would a box work? I do not have the ability to make your cool invention
i bet you don't need all the hardware. you can probably use big rubber bands to hold the form in place.
The Lexan to build this costs about $80. Will plywood work?
Does the Box have to clear and made out of plastic?
How about triangular( pyramid) shaped ones. Or dodecahedrons!
Or how about make the entire alphabet
we grew a square honeydew (by accident) it was in a cement block we used to &quot;fence&quot; the garden with.
wow i love this
I wonder if this would work with tomatoes, or if the boxes would be too heavy for the vine to support. Another thought I had was two-liter pop bottles (watermelons with feet; they'd also be good for watermelon spikes :P), though I'm not sure if the fruit wouldn't split the plastic. I might experiment with this.
to quote Eurotrip &quot;Gotta love that exchange rate!&quot;
<h2>does it taste diffrent like sweetness</h2>
soil might change the taste, also chemicals, water, but thats all that might change the taste
nope exactly the same exept shape
Wow how did you make large text??<br />
&lt;h1&gt;like this i guess&lt;/h1&gt;<br />
That is so awesome how you can grow square watermelon and sell them for $82.00
Yeah, but you have to live in Japan for that to happen. Everything, large fruit especially, is expensive over there.
1st of season/perfect are more expencive
in a historical note I believe this was started in china and in most recently the chinese made melons with the mascots from\for the bejing olimpics
would it work with apples? then you would cut a small cube from inside an fill it with caramel and chocolate syrup... hmmm....
I think if you made this box and put a pipe on the middle,you'd have a holed fruit of which you can stuff.
will the fruit grow around it?
It should.I've seen Mickey shaped ones in Disneyland too.
I think those are regular apples with marshmallows for ears.
I said that further down.
you can use a cinderblock.
