  1. I am not sure if this is the appropriate place to post this. I have been into Tesla coiling for 4 years or so now. I just recently revamped my medium sized Telsa coil so it would be much more efficient. I just need to know if anyone here can help me about HV capacitor advice. Here are some pictures of my capacitor. http://s515.photobucket.com/albums/t360/tealman535/Tesla%20Coil/ It the right value and everything I just need to know if anyone here believes that the leads are perhaps too close together. The top and bottom leads are in direct connection with the the HV Transformer. So there is potentially 15kV at the left and right of the capacitor. I hope there will be no problems with arcing across the leads. Thanks. Tim Ambrose: Teenage Inventor/Scientist
  2. I still would like to know which of these two is better for keeping bromine? http://dbhs.wvusd.k12.ca.us/webdocs/AcidBase/Lab-AcidBaseTitration/Bottle-GlassStopper.JPG or http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=180207930334#ebayphotohosting Thanks.

  3. Could you show me a picture of the type of bottle and Teflon stopper you are describing. Will something like this do? http://cgi.ebay.com/VOLUMETRIC-FLASK-25mL-25-mL-A-PTFE-Stopper-KIMAX-NEW_W0QQitemZ180207930334QQihZ008QQcategoryZ11812QQrdZ1QQssPageNameZWD1VQQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247 Tim Ambrose: Teenage Inventor/Scientist
  4. Is there any way I can purify it? I cannot afford an entire distilling apparatus. I don't have a retort. Sorry guys, looks like I just can't make bromine at this point, I'll have to wait a few years before I can afford all this. Tim Ambrose: Teenage Inventor/Scientist
  5. What about this kind of bottle? http://dbhs.wvusd.k12.ca.us/webdocs/AcidBase/Lab-AcidBaseTitration/Bottle-GlassStopper.JPG Bottle-GlassStopper.JPG (JPEG Image, 640x480 pixels) Again I submit my question that nobody answered: - Which method is recommended for making bromine? (Electrolysis of sodium bromide solution or carefully adding HCl to a solution of sodium bromide and calcium hypochlorite?) Tim Ambrose: Teenage Inventor/Scientist
  6. That's what I was beginning to wonder. Thanks for the info. However, I would like to know the specs on those bottles please. - Are they amber bottles? - Do they have plastic screw caps? - How much does it help to tightly close the bottles with teflon tape? I would appreciate it a lot if you could tell me these specs. Thanks in advance. Tim Ambrose: Teenage Inventor/Scientist
  7. Thank you for the reply. Further info: - How thick should the layer of sulfuric acid be that I float on top of the liquid bromine? (is there a volume or weight ratio to figure it out?) - Can anyone provide a link or instructions on the consentrating of sulfuric acid by the heating method? >> What kind of vessel should be used to do the heating? >> How can I do this without a bunsen burner? (This is what I do have) http://www.chefdepot.net/graphics8/portable_electric_burner.jpg portable_electric_burner.jpg (I have beakers and flasks and even an alcohol burner) http://www.unitednuclear.com/alc1.jpg However I do not have a support stand to properly use the alcohol burner. http://www.unitednuclear.com/tripod.jpg Perhaps there is still a way I can use the burner if anyone knows a make-shift way. Thanks Again. Tim Ambrose: Teenage Inventor/Scientist
  8. Just a few simple questions. - Why exactly do I store it under sulfuric acid? - Why won't the bromine react with the acid? - Will the bromine be diluted in the acid or will it stay separated at the bottom of the glass bottle? - I have some 10% sulfuric acid, will this work? - If not, how do I concentrate it safely? I appreciate your help. Thanks. Tim Ambrose: Teenage Inventor/Scientist
  9. Really, how did you do it? (which method did you use?) Tim Ambrose: Teenage Inventor/Scientist
  10. How exactly do I know when to stop adding HCl? I understand all the safety procedures and everything. I have carefully read this entire thread. How much of calcium hypochlorite and sodium bromide do I add initially? (as much as will dissolve?) Basically when does the reaction stop yielding bromine? Additional questions: - What should I store the bromine in? - If I keep the bromine very cool, will it evaporate more slowly? - What do you recommend to suck the bromine out of the bottom of the beaker? Thanks for your help. Tim Ambrose: Teenage Inventor/Scientist
  11. Unbelievable, not a single one of you mentioned my favorite. (I think) (not that I am trying to say you are all wrong) In my unique opinion, Bromine is my favorite. It is very nasty stuff. Nasty here withholding the reference that bromine reacts with nearly everything, is virtually uncontainable, is derived from the greek word brómos meaning stench, and is a very dark crimson liquid. Other attributes that catch my interest: •It is the only liquid non-metal element. •If temporarily contained in an open container at room temperature, it will soon evaporate itself away. •556,000,000 kg of bromine was produced in 2007 alone. •Although it reacts with most metals to produce a pyrotechnic display, (as seen in link number three) it is primarily used for fire retardants. In case anyone cares... I was introduced to element collecting by my good friend Dave who owns a Neon sign shop. (he has barrels of magnesium turnings and 20 pounds of mercury) I have been collecting for a little over a year and currently have 37 elements out of the 86 that are obtainable by someone like me. Ironically I do not have any bromine in my collection, I will within the next two weeks though thanks to this thread: http://www.scienceforums.net/forum/showthread.php?t=11004&highlight=bromine Tim Ambrose: Teenage Inventor/Scientist
