Nice dimple project. What will they think of next, glass bottom boats? :)

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?

it may well work but this idea is so stupid it got to be American
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.

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.
.99 is .99. This is free!
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)

"Use a lighter to "soften" the edges of the cut space"

Brilliant, original Idea... Brilliant suggestion by Conch.

Ok, brilliant idea notwithstanding, I feel you must instruct the reader to keep the cap on. I know the illustration clearly demonstrates that; nevertheless, some poor confused child might take a while to figure it out.

Further, how on earth can you let this budding young scientists question go unanswered? Please do tell us how we can make a diving mask out of a soda bottle!

Some new fuel line (or some other small hose) would work well to make it more comfortable. (Just cut a slit down the length of the tube and put it over the edges of the hole in the bottle.)

nice drawing
I'm a little bit worried that youngsters might hurt their eyes if they don't put some sort of soft stripping around the edge of this waterscope. Perhaps you should include a warning to be careful of stray bits of plastic.
pretty cool!!! ima try it
cool!!!!!!!!!
