So we boiled an egg tonight originally to be part of dinner salad. While peeling the shell, I was thinking aloud that if only we had a glass milk bottle we could do the experiment of getting the egg into the bottle. Promptly, my husband reminded me that I did bring a bottle from Finland.
So I got the bottle out and put the egg on the mouth of the bottle and ofcourse the egg wouldnt fit into the mouth and was sitting there pretty.
This is what we did to get the egg into the bottle.
Great!!! Now that the egg is inside, how do we get it outside?...one way is to use baking soda and vinegar but wanted even simpler one. So, borrowed the idea from our film canister rocket experiment and used Alka-Seltzer tablets instead....
Have you read bout Jack Andraka? He is a regular 15yr old attending school..What makes him not so "regular"? He is an innovator...He came up with a test for cancers such as Pancreatic, lung and ovarian cancers that costs only pennies and is almost always accurate. The test can be done from home or anywhere and much faster than the tests that are available today (which cannot be done from home either).
Here's an interview in Forbes on him. Encouraging him to "figure out" things and experiment to get answers is how he says he got interested in Science....Never fails to play with Science right...
I was getting ready to write another experiment in the blog when my hubby dear sent me this video to watch. Its just so cool that I decided to write about this instead.
Nano technology and Nano science are relatively new fields and there is a lot to learn but are also very fascinating subjects. To get an idea about the scale of Nano-technology, imagine this: a single human hair is approximately 80,000 - 100,000 nanometers wide!!! So, we are talking about how things can be manipulated at that minute scale.
A company called UltraTech came up with a new product called Ultra-Ever Dry..A liquid/spray that can be sprayed on almost any surface (or they claim) and it will repel water, oils, atleast limited number of acids!!!. Imagine a car coated with this would never need a wash again:)
Here's a cool video of how the product works. Wish I could get more info as to how it works but ofcourse it would be their secret not to share right...The only info I could find is that the nano-coating relies on a barrier of oxygen/air to form the barrier on the surface of the material it is coating. Meaning the surface does need to be exposed to air (and so cant be used inside a pipe which is under the ground?).
Here's a video that shows how it works....
Disclaimer: I am not promoting or advertising for the product....just a cool video showing how nano technology is being put to use for practical uses....
Unless you live in a place where there is snow all around you right now, wouldn't it be fun to make some snow in the warmth of your home and play with it without it melting away?
This "instant snow" comes in a powder format. Just add water to it and it almost instantaneously expands upto 100 times its original volume. It is spectacular to watch it puff up. It feels like real snow to touch and you can dry it up and make it puff again and again...You can't eat or make snow cones with it unfortunately.
What is "Instant snow"? - Its a super absorbent polymer called sodium polyacrylate. You find this in baby diapers!! yes, you can open up the baby diapers (before they are used ofcourse) and get the powder out and use it as instant snow too.... or you can order it from various sites including Amazon and try it out.
