Grow a square watermelon

Grow a square watermelon
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.)

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.

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.

That is so awesome how you can grow square watermelon and sell them for $82.00
Jun 10, 2010. 5:22 AMbFusion says:
Yeah, but you have to live in Japan for that to happen. Everything, large fruit especially, is expensive over there.

would it work with apples? then you would cut a small cube from inside an fill it with caramel and chocolate syrup... hmmm....
Jun 11, 2010. 8:33 AMpaperclip32 says:
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.
Jun 12, 2010. 8:16 AMindestructibleguy says:
will the fruit grow around it?
Aug 22, 2010. 8:17 AMpaperclip32 says:
It should.I've seen Mickey shaped ones in Disneyland too.
Nov 14, 2010. 9:06 AMchocogrape says:

I read about these in an old magazine witch was about 20 years old so its not exactly a new idea :)
Jun 12, 2010. 12:49 PMmavr1ck1 says:
So what. Writer didn't say it was original, just described how to grow it square. Why would you want to tear them down, it makes you look small and weak.
Nov 2, 2009. 8:34 AMp88lux says:
True.. Disneyland grow their cucumbers in the shape of mickey mouses head.. seen on the travel channel a few months ago..
