The fourth installment of the Kate the Chemist fiction series that shows kids that everyone can be a scientist! Perfect for fans of the Girls Who Code series.
When Kate's brother Liam is having a science-themed birthday party the very same day that the science club in Kate's school is planning a special rocket launch experiment, Kate isn't sure how she'll manage to do it all: be a great big sister AND a great science club member. But with a little help from chemistry--and her friends--Kate figures out a way to be in two places at once. That is, until she is late to pick up the ice cream cake, which means Liam won't have a birthday cake for his party! Will science be able to save the day?
From Kate the Chemist, chemistry professor and science entertainer as seen on The Late Show with Stephen Colbert, The Wendy Williams Show, and The Today Show, comes a clever and fun middle grade series that is the perfect introduction to STEM for young readers!
Make Your Own Rocket! Experiment Inside!

"It's a great introduction to the basics of Chemistry that is readily accessible to a variety of ages . . . . The way the everyday chemistry is blended in is done seamlessly, and has [me and my ten-year-old son] noticing how we are all doing a little bit of science every day." --GeekMom.com

Perfect Flavor: NONE
Style: Unflavored (Pack of 1)
I see reviews writing "it tastes bad". Get over it you big babies! It doesn't. I have an allergy to peppermint and other unnatural man-made toxic flavorings and this is perfect! After the first few times the flavor is irrelevant and you get used to it. It cleans and cleans well. I don't wake up after brushing before going to bed with a mouth full of slimy coating on my teeth and bad aftertaste like I did with the other fake flavored toothpastes. I use Cleure for all my teeth brushing and haven't had any dental problems. The paste is smooth and I don't have irritation. It's great...I just wish the price point was a little lower since there's less added garbage in it.

Gentle, No harsh ingredients, no taste!
Style: Unflavored (Pack of 1)
This is the toothpaste you want if you want no additives or nothing.
There's really no taste to it, but that's the whole idea you're getting no additives no nothing.
It does have baking soda, and xylitol these are two great ingredients but overall it's very gentle.
If you're having any problems with skin or anything and you feel it could be from either fluoride, mint flavoring, SLS, or coconut oil or all the other stuff they put in there give this a try!
I'm on my second tube!
Yes you're not going to feel as super clean as the other ones but that's because it's not stripping everything off your teeth like the other ones do it's very gentle and if there's any issues with sensitivity or anything like that this is the way to go.

Good ingredients
Style: Unflavored (Pack of 1)
The ingredients in this may appear to be boring, but for a fragrance-free, flavor free, toothpaste this one is not bad at all. It has a little bit of sweetener in it and it does a good job at leaving my mouth feeling clean and my teeth polished. I am very happy with this product and it is replacing a similar product that I was not happy with. This is a product I will reorder and continue to use as I am happy with the cleanliness and freshness.

No flavor toothpaste with a high price
Style: Unflavored (Pack of 3)
Great product at a not very great price. Maybe you came across this product while searching for unflavored or flavorless toothpaste. Well this does the trick it has no minty flavor to interfere with your morning coffee or your autism. But why does less ingredients mean a higher cost? I’m looking for something bare bones, no taste, and cheaper than the toothpaste they sell at most stores filled with chemicals! Why is this so hard to find?

Acid Reflux and LPR
Style: Unflavored (Pack of 1)
I follow a dietician for those who deal with Acid reflux and LPR. Being without flavor especially peppermint, as mentioned by the dietician, can be helpful for some. I have found this to be true with this product. It seems to have helped reduce, or at least not add to, my feeling of throat and mouth burning.
