I'm going to have to defend my idea of the submarine because I still think its a good idea.
1. I really want it so I can play with my blue crayfish "Luna". I can see myself making a little tether on the back and her grabbing it and riding around the aquarium.
2. Maybe I would attach food to the sub, or really I see myself getting another RC toy and breaking it apart to build an arm that can move or pick things up. That would be new hotness
3. As far as scaring the fish goes, they'd probably become accustomed to the sub. I'm not sure if they would even be smart enough to know its a toy and not a fish.
4. RC things are fun. If it was a failure I could find another use for the sub.
5. My amazon puffer is pretty mean so I don't mind chasing him around. Yes I know that sounds very ignorant.
I'm really a crustacean lover, thats what I most see the use of the sub for. I used to catch crayfish in a creek as a kid and its a memory that makes aquarium keeping appealing to me.
Hi Carpguy
I have been busy with school and some things and haven't gotten around to it yet. However I have just set up a new 29 gallon in my basement to do some things with. I am between a terrarium or an atlantis project.
I have the picture you drew in my mailbox but it won't open for some technical reason, I'm going to forward it to my girlfriend's computer and check it out again.
The materials have been lying in my room since we last discussed it. I have some silicone gel, tubing, suction cups, glass bowl.
I think we agreed that a rectangular casserole dish looking thing would do best. Also I have been using a drill to do audio projects in my car so I'm pretty handy with that, but I think we also agreed that would be a bad idea to drill a hole at the top for the exit tube. I'm trying to remember the important thing your picture told me. I know it had to do with the way the air would leave the atlantis globe. Like if you use no tube you'll get big burps of air every other second, as the air stone pumps air into the atlantis then some is pumped out.
Now I remember, the tube has to be setup and angled just right so water doesn't go up it, but air goes out. Did we agree the tube should be angled slightly down and be at the bottom of the globe? I have 10 more days off from school so I do have the time to do some work with this now.
The next step is for me to get a rectangular clear glass enclosure I believe. I wouldn't mind doing a test with the round globe first. Something occurs to me. Since the air pressure makes the globe want to go up with some force, and the middle of the glass is the weakest, do you think it could break it or crack it eventually? Might be some consideration for weighing it down. With a rectangular enclosure putting rocks on top would be much more easier.
I'm gonna be at walmart today I'll take a look around for some more materials, and also I may go to a specialty shop for the enclosure. For the substrate would you pick sand or gravel?
