I would have to say weapons grade fissile materials like Uranium and plutonium (which is actually made in breeder reactors)

It said that the Precision Bullets are swaged with certified 6/2 lead alloy, and then a unique dry-lube formula is applied, completely encasing the precision lead core. That is awesome, I had never heard of Precision bullets before, I just might have to check them out! Thanks!

Rubber. PVC, oil (special types), mica, porcelain, tufnell, glass, teflon, silica, shellac, special varnishes in motors, and hundreds of different tyes of plastics.

Mostly quartz and orthoclase feldspar. Any number of other minerals can make up the rest.

Mostly hydrogen. There is a little bit of helium and heavier elements in there as well.

Tell me wat kinda??\nModel rockects wooden body, or thin sheet of metal, depends on the strength required...\n\nHuge rockets, alloy named duralium and magnalium, And other alloys containin aluminium and tungsten because aluminium is very light and tungten gives it strength and stablity at high temperatures\n\nU even use carbo-fiber polymere's modified to sustain heat.

Yes, what the others aswerers said is true, but if you really want interesting things to find out  you should look to the masonry drilling bits, because they work on totally different principle than normal drill bits (for wood, metal and so on).\n\nThe masonry doesn't behave like all other materials, meaning that's not plastic (it does not deform and remain deformed after that, but is a very little bit elastic), and also IS fragile , meaning that is cracking if the critical tension has been reached. Also is not homogeneous like other materials (actually is a composite material, made from pebbles, stones and cement in water).\nThat's why the drill bits for this kind of things act exactly like rotating chisel. It has an leading edge hat is acting axial (along the axis of the drilling bit) and the bit is made from the most strongest carbides (VC, TiC, WC, etc mixed with the metallic powder techniques).\nThat's only because a drill bit  made for wood/metal would be destroyed at the very first millimeters. \n\nIt's acting by hitting then rotating few degrees and then hitting again and so on (that's why I called it "rotating chisel" and its bit is acting along the axis of the drilling rod).\nThe metal/wood drilling bits are acting like knifes which are "shaving" the face of the material bit by bit, actually making a spiral (a continuous chip) with the chips no thicker than 1 millimeter, no matter the size of the drilling bits. In the same way the masonry drilling bits are not fitted to drill wood/metal.\n\nDfriend:)

Most steack knives now are made of insect resistant woods.  Usually a mix of plastics in there with wood.  But really old knives made from wood that has already been infected with termites would easily have some larva wriggling around in there.

Ah, depending on the brand of piano, the sounding boards and keys are made of different types of wood. Black keys are often made with Ebony. Cheaper models are painted or covered with plastic. Some use ivory (black AND white) and some use mother of pearl for the white keys. Felt is used to stop each string's vibration. The tuning screws and other metal workings are usually brass. The strings are steel and copper (three strings per key), depending on the pitch. I hope that helps.

fuels are hydrocarbons.  Fossil fuels, which are derived from fossils of animals which have died years ago.  Jewelry, such as gold, is simply gold...  Diamonds are made up of coal that has crystalized over millions of years.  Coins such as dimes are made up of nickel.  Penny's mostly copper, and some coins used to be made up of silver. Cookware is usually made up of tin, or iron (Sometimes silver, such as china.)  Detergent is made from petroleum which is derived from hydrocarbons.

Most are made of rubber.
