    Every Little Bit Counts
    These little gems enabled Michael to fine-tune his car to 5.000oz He loaded it a tiny bit heavy and pulled off one at a time until the digital scale read 5.000oz

    First place!
    The weights were perfect for fine tuning our car. We weighed in at just under 5 ounces through the use of the spheres and took FIRST place!

    We were able to place the small weights exactly where we needed them to balance the car.

    Nice for easy weight adjustments, when you dont know if your race scale is going to be the same as the official scale.

    Neat little BBs
    These are really small and are perfect for small adjustments. But keep them contained, because they like to wander!

    Topwater frogs
    I bought the tungsten spheres for a different reason than for pinewood derby cars. I use the spheres for sound purposes inside of topwater frog baits for fishing. I will add 2 to 3 spheres to each frog. I force the spheres inside a small opening on the bottom of frog. As I cast the frog out into the grass or lilly pad area, I will twitch the frog as I reel it back. As I do this the spheres make alot noise banging around together. Largemouth bass can hear the commotion alot easier and come investigate and hopefully for me they will attack the frog. Then the fight is on.

    Good weights
    Good weights. They pop the weight up by one tenth of an ounce per weight. One suggestion--drill an extra hole and bring the extra weights with you to the race. My scale at home weighed my car at exactly 5 oz. The official scale at the Pinewood Derby was one tenth of an ounce short. If I had had an extra weight I would have put it on at the weigh-in and improved my speed a little.

    great product
    I bought these for my son's Pinewood Derby car. They are great for adding a small amount of weight at a time. They can be a little difficult to work with due to their size but they are worth it.

    MY BBs
    The BB's are great instead of using tunsten putty or those Pinecar weights from the hobby stores. yet keep them in the bags and make sure they go to your car because they slide off and are a pain to find undera table overall they do there job.
