Testing the Waters

Update: I forgot to disclose a method for testing in the last post. For those of you interested in whether this way of waterproofing a cochlear processor really works and if you're hesitant (like me) to put such an expensive piece of equipment under water to be the guinea pig, here is one of the simple tests I used.
Take a Lok Sak, place a small piece of bread, seal it up, and place it in a bowl of water. Set a timer. I chose bread because I thought I would easily be able to tell if it took on any water. Find something to use as a paperweight (I used a jar of buttons) that will push the Sak to the bottom. Set the timer for as long as you want to wait - you will not see ANY water anywhere on the inside of the Sak!
My 10yo daughter was very excited that the bread was completely dry when she took it out of the Sak and ate it!

I have tried the Sak out using food, money, AA batteries, and Kleenex, just to name a few. I've never found any water inside! Best of all, it worked with the processor!

"Deal with thy servant according unto thy mercy, and teach me thy statutes." Psalm 119:124


  1. What great tests! That gives me a lot of confidence in the aloksak. So glad William will be able to enjoy fun in the water AND hear all the wonderful summer sounds!

  2. I love your 10 year old's reaction. :) turn her into a scientist and she can do all kinds of experiments.

  3. That is a brilliant idea. Those baggies look a lot cheaper than purchasing a sealing machine, too! I'll have to share this with the family of an 8 year old we know with CI's.

  4. J! Thanks for this! I have a new reference for families! Have a great day!

  5. LOL... yeh it works. We used cheal zip-lock. Nothing else available here.. (Norway)

  6. btw.... OK if I put your blog in Lotte's blog?
