    ohhh the things you see working at home depot every day..

     

    that reflectix is just like the windshield shades... its made up of a bubble wrap with a silver type foil. Im sure its very effective.. but I don't know about use in the engine bay

     

    Home Depot also sells the following products which I believe are excellent, cheap alternatives

    *did you know that climbers on their attempt to reach Mount Everest stay at middle camp, at 20,000 ft MSL for 5 weeks to acclimate their body to the altitude and produce enough red blood cells?!

     

    *did you know that your body burns calories when consuming iced water, since your body has to "warm" up the water to core temperature?

     

    *did you know that hot, spicy food speeds up your metabolism?

     

    *did you know chocolate contains caffeine?

    Well, no...

     

    If the brick has is already falling (as implied in your original quesiton) when you shoot, the brick has a head start. If its been falling for about 400 feet then its reached its own terminal velocity. In either case it will be falling faster then the bullet shot out of the gun until the gravity accelerates the bullet to its terminal velocity. Drag also affects the terminal velocity with a brick having a drag coefficient of 2.1 and a bullet in a ballistic trajectory having a drag coefficient of .3.

     

    So, I'm will to bet a bunch of money that you're not going to hit the brick if you aim right at it.

     

    Also depends on how high the brick was dropped and the height of the gun..

     

    If the gun was 5 ft from the ground and the brick was dropped say 15 ft above the ground, and you shot "upwards" towards the brick...although gravity is affecting the bullet, the bullet is vertically ascending at an angle... so this wouldn't necessarily workout.

     

    But say the gun is 5 ft from the ground shooting parallel with a flat surface hoping to intersect the brick at exactly 5 ft above the ground I could see that gravity would affect both objects in that manner

    Ken Block defects to Ford

    He isn't in the WRC yet.. Ford will be racing in Rally America.. he will be doing some testing in the WRC and may have a guest appearance from time to time to see how he does. I believe he raced an older RWD Celica in Finland last year

     

    Block would be one of the few and first USA drivers in the WRC.
