Firstly, asparagus contains a number of sulphur containing chemicals including the amino acids cysteine and methionine ...Sulphur containing products can cause nasty smells that could be responsible for asparagus wee wee. Anecdotal evidence suggests that taking the amino acid methionine as a supplement can result in the same flavored wee wee as when asparagus is eaten, further supporting the hypothesis that it is cysteine containing amino acids are responsible for the smell.Comparative Analysis
I was unable to follow the logic how cysteine was responsible for the smell. Maybe they meant methionine? or did they mean to include both, as they both have sulfur? I don't know.
Did you know that the average computer keyboard has 100 times more bacteria lurking on its surfaces than an ordinary toilet seat?Statistics
But *why*? Is it because the average toilet seat is cleaned with a disinfectant quite often? If toilet seats and keyboards were cleaned with the same frequency in a similar manner, then the factoid would have the makings of a proper comparison.
On the other hand, I did like their osmosis experiments with the eggs, and will have to look through this site more with the kids for other cool and interesting stuff.
We are just as likely to die from an asteroid impact as we are in a plane crash?
This may be true, but *how* it's true is incredibly important to understanding the process. I get frustrated sometimes at my kid's school curriculum because they do the same thing, throw out a random factoid that does nothing to improve knowledge. I'm guessing that what is meant is that a major asteroid impacting the earth would result in massive deaths, while a plane crash results in relatively few, thus (probability of the event) * (probability of you being in the event) is greater for the asteroid case than the plane case. What irritates me is that the way this is framed can lead people to jump to the conclusion that asteroids kill people more often than plane crashes do (which is false).

That said, this site doesn't seem to be anything special. With the exception of the DNA extraction, all these experiments were already fairly old hat in the 50s (judging by the old DIY science and kitchen experiments I love to browse). And even that DNA thing has been around the internets for several years now.
If there were some added charm or great illustrations or something this could stand out, but as is.....meh. I looked at the answered questions a little less thoroughly, but the ones I did were also all very standard, well-trodden questions.
