The new improved solar cooker
Here I am once again giving you an update on our solar cooker. We have tried two different tops on our solar cooker just plain ceran rap and plexi glass. With the ceran rap it got up to around 120° F. With the plexi glass we had a problem since it was windy the wind kept catching it and it would fly of so it was exposed for a while. It got up to about 130° pretty good for not having a lid. We are hoping with week when we test it will go better since we have sturdy tape to hold down the lid on it. We are going to have a solar cooker cookout in May which I am super pumped about. We are going to be trying multiple foods to cook and see which we can cook the most of and still be delicious. We are working on seeing the highest temperature we can reach so we can quickly pick out which food will cook the best for the cookout. We are having a great time figuring this all out over it is a great expirience.

Propylene Glycol
Propylene Glycol is a popular chemical used in many personal care products. It is used to keep the product from freezing or melting. The environmental working group categorized Propylene Glycol as a moderate health issue. It alters the structure of the skin allowing chemicals to penetrate deep beneath the surface increasing the ability to reach the blood stream. Propylene Glycol has been linked to cancer, development issues, allergies, immunotoxicity, neurotoxicity, endocrine disruption, and organ system toxicity. Cosmetics can contain up to 50% of the chemical. Guys don't just think that since you don't use cosmetics it is not going to affect you. It is found in the popular drink mix mio, shampoo, conditioner, soap, acne treatment medicine, nail polish, and mascara. The chemical has been added to anti-freeze to replace ethelene glycol. Ethelene glycol is dangerous to use due to one of the facts that sometimes people spill anti-freeze and dogs will go and drink it... Not good. Propylene Glycol is worse for those with eczema and other skin allergies. For example my aunt cannot use or eat anything with the chemical in it because she is allergic to it. It makes it very hard since it is in all types of food such as ice cream, artificial sweetener, icing, and soft drinks, and most types of laundry detergents. When she eats cake or uses a different shampoo her face will swell up and she gets hives = not pretty and kind of scary to look at. It is hard to look for things with or without propylene glycol because it has many other names such as dihydroxypropane, hydroxypropanol, methylehthy glycol, 1, 2 Propanediol, and many many more. Some of the specific products that contain the chemical is Cetaphil, Aveeno, Nivea, and Arm and Hammer. Always read the ingredients on the boxes or bottles just to see what all you are taking in do a little research about the ingredients. It is always best to find an alternative, my thought process is if it is in anti-freeze and my food AND my shampoo and conditioners it is probably not good for you.
