Having trouble finding a water weasel

Before I found 5 of them Sat. I was trying to think what would be a good substitute...

I thought about ziplocs but I think the type of plastic they are made from would age really quickly in the heat.

Ever see a ziploc that has been out in the sun for a couple of weeks? they turn cloudy and become brittle.

Is this what you are looking for?

They are usually on the junky toy aisle at drugstores, discount stores, etc. I found mine, called a Water Weiner, LOL, at Rose's Dept Store, sort of like an Odd Lots/Big Lots store type thing here. Never saw one at WalMart.

It really dont have to be a zip-lock either. Make it out of anything you want. Got a babyfood jar? Waterproof the probe on your thermometer, place in jar of water and Saran Wrap the top (to prevent the water from drying out). Let your imagination run wild and use whatever you have available.

The only thing the WW is doing is creating a mass that heats and cools at about the same rate as an egg so you dont drive yourself nuts adjusting temps. In fact, your improvised WW dont have to be egg size, it can be any size, it is only there to show what temps are in your incubator steadily (keep in mind if you use a big heat sink and your temps fluxuate, you wont see it as easily, hence the reason for keeping the WW at egg size but a quart mason jar would work fine). The egg size just will show you if your wafer is going south and keeps room in your encubator for eggs, not glasses of water.

The smaller the incubator, the more prone this temp swing seems to be. Also, the heater is at the top, Im sure everybody has watched the light turn off and watched the temp plumit only to have it spike when the light comes back on. Once you put the WW in the incubator, you can see the temp is fairly steady. I bet alot of wafers got thrown out way before thier time because of this.

The temp swings are not as much of a problem or seen in a larger incubator and ones that have a fan to circulate the air.

Using a WW as a heat sink is an old trick for refriderators (or warming cabinet) when you want a very narrow temp range but dont want the compressor cycling on/off all the time. Actually they dont use a WW, they just put the probe for the fridge in a glass of water. It steadys the temps shown and creats a longer run time so its easier on the equipment.

I did a lot of searching for this Water Weasel
in my area, with no luck.

But I did purchased it finally from this website

They also have a very good detailed explanation
of the Water Weasel on that web page.

I emailed them and they sent me a PayPal Invoice
to pay for them.

Make sure in your email you put your zip code,
so they can figure out the Shipping cost.
