    My Daughter had to come up with a project for the school science day.

    I was a little surprised when she asked me about doing somthing with the NERF blasters as she hates being ambushed by her brother when we are fooling around.

    Anyway I suggested we try and work out the speed of the darts when fired from a range of blasters. I did some googleing and found a couple of instructionals about using an audio chronograph to calculate NERF speeds so we thought it would make a good project. Her brother was even keen to help.

    Here is some of her project

    Nerf Project for Science Day  NB1

    Nerf Project for Science Day  NB2

    And some results

    Blaster
    Night Finder Average Speed 17.66 MTRS/SEC
    Maverick Average Speed 14.04 MTRS/SEC
    Modified Long Shot Average Speed 26.15 MTRS/SEC

    (Longshot has Brass Breech and BT spring)

    I hope you enjoy. I know I did, it was a project I didnt mind helping with and its good to see kids excited about science. There was a certain Mythbusters feel about the whole process

    Cheers Pete

    I love the idea, I don't teach science but if anyone asked me to recommend to them an idea for an experiment, I'd give something like this

    Hey this is a cool way to measure velocity =). I'll throw it in the modifications directory since it might be useful.

    Yes...VERY useful indeed.

    This could be a way to be able to quote genuine performance estimates about your blaster.

    Combined with a good old fashioned measurement in feet it would eliminate bulls#$%ting and exaggeration.

    Also in some states don't they (them) stipulate that anything discharging at over 180ft/sec is an actual weapon?

    I wonder if I couldn't use my Sony video editing software, which has a very accurate timeline with a separate slot for audio.

    I could probably use my iphone or bloggie to record the results, then upload it onto my laptop and measure the time that way.
