    I know this isn't cycling related...

    But I thought this forum would appreciate it anyway...

    This is incredible: so simple, yet the effects are huge. It's also a great example of refraction. I'm going to use this video in my 8th grade class when we discuss the behaviors of light.

    Maybe I'm confused, but didn't we already have a thread about this? Anyhow, it's a great idea and a good little film.

    I'm not sure, my ex sent me a link to it. But I don't remember it here.

    55 watt bulb? That's pretty cool. Although I imagine that bottle has to be replaced every 6 months or so.

    Why? I thought that the plastic will last for centuries and they add bleach to the water to keep it from clouding up.

    The only issue I see is how they waterproof the join between the roofing and the bottle, but I suppose they'd be celebrating rainfall, so a leak that big would be worth overlooking.

    Not a new idea.

    Seems like it originated in Brazil around 2002.

    In this video they use 35mm film cans over the screw top to protect them from the sun.

    I thought the bottles would cloud over in the sunlight and then leak. But it might last a while according to this source

    I know a better experiment about refraction,but it for adults only.It involves flashlights and saline/silicone filled bags......
