Question: Should I eat a box of 12 fresh hot glazed Krispy Kreme donuts in the name of science?

I have been so good this holiday about eating healthy and avoiding snacks. BUT, I have been craving fresh hot glazed donuts from Krispy Kreme for weeks now. I have even dreamed of them. I know it sounds silly, but I just HAVE to have one or more.

The Proposed Experiment:
I think I could possibly consume 6 in one sitting , but don’t know if I can eat 12. Should I see if it is humanly possible for me to eat 12?
Should I stop at satifaction, or pig out and get it out of my system? OR, should I keep on avoiding them though they call out to my inner being?

You may answer as you wish, no offence will be taken. Please use child friendly vocabulary. (No ugly words please)
Uh, yeah 20 is far too ambitious. I dont want to vomit.
I will let you folks know the outcome. Ya know, for Science and all!

Answer: OMG! I love Krispy Kreme donuts. I swear there’s got to be crack in them or something, they’re so addictive. I’ve had about 3 or 4 in one sitting but 12? Honey, you’re tummy is gonna be hurting! And to think of all that sugar in your body at once, surely you’ll get sick to your stomach. But if I were you, I’d go ahead and indulge a little. I mean damn, you’ve been dreaming about these donuts you might as well, right?

Fun Volcano Eruptions! – Quirkles KOLR 10 Vinnie’s Valentine Volcano Science Experiment

Question: How can I expand my science fair project idea? Real life application needed…?

For the science fair my partner and I made flute headjoints out of various materials. We were planning on blowing through them and using sound frequency wave analysis software to see how many overtones were present in the sounds. Then based on that we would come to a conclusion about the different metals and how they affect the vibrating column of air inside the flute. I’m starting to think this isn’t enough and I’d like to connect the project with a real life application. Does anyone know of a practical usage of vibrating columns of air in tubes (one that is comparable to our experiment)?

Answer: The animal or human ear / ear drum!… On a different note (pardon the pun) You could also look into hypersonic sound (which is more directional) then you can aim two non-audible signals at slightly different kHz say 50kHz signals and another at 60KHz.. if they are phased correctly they should yield a 10KHz hear able sound where the two non audible sounds are in the same location. Does that sound like fun?

Google Project 10^100 – Virtual World – Idea (project 10 to the 100)

Question: i don’t have much knowledge of electronics. but i would try to start from a Small project. can u suggest me ?

Answer: Below I have included a few options that may help. There are several electronic kit out there that let you experiment with electronics and guide you through how to wire the different projects. I also recommend getting a multimeter for testing circuits. Other options available are robot kits, remote control car kit, etc. I personally had one of the old radioshack kits when I was a kid and learned a lot from it.
