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!

"Proves that science and fun go together like molecules in a polymer."--School Library Journal
"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

Not Boerboel proof
I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately.
She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole.
It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.

Favorite Toy
Size: Medium/Large, Product Packaging: Standard Packaging
My dog is a 3.5 yr old mix and this toy has been her favorite toy by far for three years. She likes it as a squeak toy, loves it as a tug toy and can't live without it as fetch toy. I roll it on its edge outside and she chases it - sometimes it take cool bounces or swerves and sometimes its just rolls straight and fast and whatever it does she can't get enough of it. She demands we play fetch with it at least three times a day. She's not a great releaser of fetch toys so there's plenty of tugging play involved too. We've had three of these over three years, but she's 75 pounds of muscle and it gets a work out every day so it's a really tough toy. All dogs are different, so I don't know what your dog will think, but it's been a fantastic toy for our girl.

So Bad
Size: Medium/Large, Product Packaging: Standard Packaging, Size: Medium/Large, Product Packaging: Standard Packaging
Had high hopes for this toy as Kong is fantastic with aggressive chewers as or Lulu is. This toy didn't last 30 minutes before she was able to tear it apart. The rubber and plastic are not of the same quality on nearly all there other toys she has. Have found better toys for half the cost. Kong needs to do better.

Very cute, good quality
Style: Lambchop, Size: 10", Style: Lambchop, Size: 10"
Our Two year-old Great Pyrenees rescue loves her Lambchop. She’s fairly gentle with it, but it did accidentally rip so we had replace it since she loves it so much. No fault of the product. The product is very well made, She just got a little rough with it.
