    try curling the cut edge of the pet bottle inward by using the body of a "not so hot" soldering iron maybe 30 watt run the soldering iron along the edge heating the plastic to shrink toward the inside of the bottle. i have curled pet bottle edges on a flat iron to make small pots it sort of stiffens the edges by the curl formed

    Great idea! Sometimes simplest is best. The comments about sharp edges around the cutout are valid, but a touch with sandpaper or even an emery board should solve the problem. A cigarette lighter would work too, but may not be a good idea if your little oceanographer is helping with the construction.

    Little builders will need to learn to play.., uh, er work with fire at some point. This would be a good as place as any to start. With adult guidance of course. A long nosed fire shooter will keep the heat well away from young, and old hands. Does anyone use matches anymore?

    Any idea that works can't be stupid. No matter what creed, economy, gender, nationality, politics race, or sexual preference. Apologies to anyone I failed to mention.

    Great idea & so simple to do. The kid's will get great use out of this...many thanks!

    I made one with a black 5 gal. bucket ,you simply cut out the inside of the bottom of the bucket and cut a round piece of plexi glass to fit,then use clear silicone to seal it in.this one works great for finding fossils and Ive used mine to find things people have lost at a swimming hole I sometimes go to,rings,watches coins and such.

    Nifty idea but this is dangerous considering that the plastic will have sharp edges when you cut the bottle and a 2-liter is what, $1.30 nowadays? A pair of cheap goggles are $.99 at most any store.

    Um...when I buy a 2 liter bottle, I'm buying it for the pop and the bottle is usually something for the recycling bin, so finding a quick project that could be done at the beach is a winner. As for the goggles, the cheap ones leak and break easily.

    She is sooooo checking out that fine piece of meat, known as Tuck's bottom.

    Oh I hope not thats Tuck's sister! ... on the sharpness thing ... there is no way that edge will hurt little faces. My two tried it on the weekend and found some yabbies in the creek.

    Remember children learn from making mistakes WE MUST give them the space to do this.

    1)Use a 3 Liter Bottle 2)Use a lighter to "soften" the edges of the cut space 3)Goggles are hard to use if you are in a kayak and are trying to paddle at the same time whilst looking for lobsters to catch.

    lol....if you put your face in the water with any viewing device while kayaking....the correct term becomes swimming. But, if by some chance you are capable of paddling a kayak while your face is in the water...please make your own instructable with videos! :)

    awesome! i'm always looking for crafty stuff to do with my niece and nephew when we go camping in the summer. This is perfect! And i love being able to recycle stuff i already have. I'll bring some duct tape to wrap on the cut edges to protect little faces and then we'll be good to go. Thanks for great outdoor project. :)

    Very cool! Thanks...my nieces and nephews will love this. I think this is totally safe the way it is but for anyone who thinks their kids could get hurt...just put some duct tape around the cut edge :o)
