Before you can pack materials using dry ice, you'll have to purchase some. You can buy packages of dry ice at most butcher shops and grocery stores. Some UPS stores or FedEx stores may sell dry ice. Once you've obtained dry ice, you need material to pack it safely. Dry ice releases carbon dioxide, which can be hazardous if released through the package rupturing. A rupture can be caused by pressure pushed down on a package during shipments. Therefore, the material you use should allow the release of some pressure. You can use good quality fiberboard, also known as corrugated cardboard, which you can purchase online or at a local hardware store. You can also use plastic or wooden boxes to ship with dry ice. Do not use steel drums or jerrycans to ship dry ice. It's a good idea to layer the box with Styrofoam. Some even advise mailing the box in a Styrofoam cooler, which you would then place inside another container. Make sure the Styrofoam you use is at least 2 inches thick in length. When packing your container with packages of dry ice, use gloves. Dry ice is very cold and can cause serious burns if it comes into contact with bare skin. Wrap the food in plastic wrap or place in paper bags prior to packing. You want to make sure the food and dry ice are packed together tightly. Use newspaper or cellulose to make sure it's packed tight. This provides extra insulation, keeping your perishables fresh. If you're using a Styrofoam cooler, do not seal it completely as this can prevent the package from releasing pressure. Packs of dry ice should be on the bottom, followed by food items. You should alternate between dry ice and food items, filling in excess gaps with bubble wrap and newspaper, until the box is full.

Summary: Purchase packages of dry ice. Get the right quality material for packing. Add a layer of Styrofoam to the box. Take precautions when handling dry ice. Pack the box.

You can find one in the woods or you can buy something which is similar, like a 2" diameter dowel rod.

<\/p><\/div>"} Real ninja swords were short, allowing them to fight it close combat and move more easily. A good rule of thumb is for the blade to be the same length as the distance from your elbow to the tips of your fingers. Just be sure to leave an extra 4-8" for the handle on the end. Shave off the bark using a knife or whittling tools. If you are using a dowel rod, this will not be needed. Using a knife or whittling tools, carve the sword blade into the shape you want. Point the tip and add some curve if you want to, but real ninja swords probably had little curve and an angled point. Once you've got the rough shape that you want, use sandpaper to get the final look right. Sandpaper will make it easier to get the shape just perfect, since it only removes a little at a time. Using some electrical tape, wrap the handle of your sword. Cut a piece of cardboard so that it will fit down over the blade. Paint it black and slip it on to create the hand guard. Do this from the blade side, not the handle. Use some extra tape to really seal the hand guard to the main part of the sword. You can make your sword look even cooler if you want to, by painting the blade silver. Use tape and newspaper to protect your handle and then use silver metallic spray paint to paint the blade. Do this outside. When it's done drying, enjoy your new sword!
Summary: Get a thick, straight stick. Cut the sword to length. Clean up the wood. Carve the sword into the desired shape. Sand the blade smooth. Wrap the handle. Create the hand guard. Slide the hard guard onto the sword. Tape the hand guard in place. Add finishing touches.
