Bending, Shaping and Strengthening Foam Armor (Cheap and Easy method)
Putting complex bends and curves in EVA Foam armor can be tricky, since the foam is very elastic and flexible. Parts don't always like to hold their shapes, and the prevalent method (from my experience reading costume forums like therpf) for shaping foam armor parts is to use a heat gun. I didn't have a heat gun, so I decided to apply something I discovered when I was making my Iron Man Mark 3: paperclips are surprisingly good at holding form and shape.
My method basically involves cutting lines into the inside of an armor piece, lining the cut with a paperclip and then sealing it back up with hot glue. The best part about this method is that you don't have to go out and buy a heat gun if you don't have one. Additionally, it is really easy to re-shape if you so desire, and the paperclips actually do strengthen and stiffen the parts.
The materials you will need:
1) Foam armor part (pepakura is the most popular method for making foam armor)
2) Paper clips (Use large ones because they are thicker and sturdier)
3) Hot Glue gun
4) Pliers (Needlenose, and optionally diagonal cutters as well)
5) X-acto knife
In this instructable, I will show a fairly simple method to form, shape and strengthen foam armor, using an Iron Man helmet made from EVA foam floor mats.
CAUTION: Be careful when placing cut paperclip bits as these are sharp and can easily penetrate skin. I have placed this warning again at the end of the Instructable, so please follow safety precautions and exercise good judgement while building!

Easy Topsy Turvy Tomatoes for Cheap
1) The dirt. Have it ready to use.
2) The hooks. Find the spot you will hang the tomato plant. The south side of your house is probably the best, as it will get the most sun if it isn't shaded. I drilled out the holes first.
3) Cardboard holders. These will keep your tomato plant in the bucket. I cut a couple of squares, approximately 4" x 4" or 10 cm x 10 cm. Then cut into the middle and make a hole that's big enough that your full grown tomato plant won't be squeezed.
4) The 5 gallon bucket. Cut a hole in the middle of the bottom, approximately 2" x 2", or 5 cm x 5cm. My technique was to drill a hole with my largest drill bit, and then get in there with some tin snips to do the cutting.
5) The tomato plant. Carefully remove from it's previous pot. Loosen up it's roots, removing all the extra dirt into your dirt supply. Gently work the roots in from the bottom, supporting the stem while you do. Now slip a piece of cardboard over the stem, on the inside of the bucket. Repeat with the second piece turned 90 degrees from the first. Many times they will wind up interlocking, which is cool but unnecessary.
6) The dirt part 2. FIRST CHECK THAT THE STEM IS CENTERED IN THE HOLE. Now for the hardest part, you will need to hold the plant with one hand (or find an assistant) and fill dirt in with the other.
7) Hang it up. Pat yourself on the back. Water, and enjoy tomatoes in a few months!
Two notes: I would rather do this with clay containers, but was in a hurry. Clay is better than plastic for plants, and because I did this in plastic it can't be called biodynamic.
If you want to know when to transplant, and discover all sorts of secret powers, check out the Stella Natura biodynamics calendar. I'm not associated with them, but think they are awesome.
