what soda does to your teeth experment

Most of the discussion on drinking soda has focused on high fructose corn syrup and its detrimental effects on blood sugar and weight. But, what about your teeth?
Today, we are taking a page from a kindergarten teacher's playbook (thanks, Greta!). This teacher uses a very visual experiment to help her class of 5 year olds understand what happens to teeth when you drink soda.
I have heard that if you immerse a baby tooth in Coke it will dissolve in 24 hours. I checked into this myth and it isn't true. What IS true is that soda contains acid that will dissolve the enamel of teeth over time.
Our experiment is simple. Take a hard boiled egg and immerse it in Pepsi or Coke for 24 hours and analyze your result.

The obvious conclusion for the 5 year olds is that you need to brush your teeth. They take toothbrushes and scrub all the color off the egg to mimic brushing their teeth.

But, what does this experiment mean for us grown ups? Well, I found a study that concluded that prolonged exposure to soda can lead to significant tooth enamel loss (see here: Acids in Popular Sodas Erode Tooth Enamel).http://www.livescience.com/7198-acids-popular-sodas-erode-tooth-enamel.html

Big giant slime ball!!

This was such a fun activity! All you need is two boxes of slime baff and a wubble ball. We got the super wobble ball. So to make this epic slime ball use the tube it came with and place it in the ball as directed on the instructions. Next pour in all the slime baff. After that grab a hose and hold it in the tube. At first we did not let it get that big, too scared of it popping.  The kids including neighbor kids loved it. We played kid bowling and let this roll down the driveway. The kids thought it was the best thing ever to see this ball bend around them with out breaking. (will attach videos at the end) 
If you look close you can see the slime forming. You can barely tell it started as a blue ball. 
After awhiel of play we decided to make it bigger. We attached the tube and hose again and let it grow till the kids said stop.  Below is how big it got moments before popping.  This had to weigh a lot. Once the ball popped all the kids had fun playing with the slime. Two actives in o…

Pokemon balls for pretend play

We have made a huge Pokemon ball before but with the new Pokemon game out we decided to size it down a little and make it hand held. We still used styrofoam balls and choose some different type of Pokemon balls to make. So even though none of my kids can actually play the new game that has become such a hit they can still join in, play with their friends and have fun. 

Cookie cutter pumpkin...fail?we tried it..our results

When I first seen this idea floating around I got really excited...people made it seem like it was a easy clean way for little kids to help with pumpkin carving. Well after buying a medium pumpkin questioned started to come up...like how is a kid going to get a cookie cutter threw the hard skin of a pumpkin?...anyway here is what happened....
I took the pumpkin first to try this out...cleaned it and let it dry...Then I used one cutter and tried pushing it into the pumpkin...yep that wouldn't work for anyone..skin is way to hard...So then I got out a hammer and started banging on this ...sounds easy right? nope!
The cutter kept slipping from its first spot. So being a good mom I am I called out my 5year old to try this..gave him the hammer and guess what second hit, he missed...hit my finger though...dangerous, maybe?..Anyway even with the hammer this is not easy..you have to hit these with force and that's not any force my 5 year old had...I couldn't imagine him trying wi…
