Things are rarely ever normal in Reeko’s Mad Scientist Lab and this week was no exception.
During his latest no-scratch scraper experiment, he was interrupted by a raging group of
lab monkeys who apparently have just heard about the Theory of Evolution. They are
outraged that some scientists have proposed that humans descended from monkeys. The
lab monkeys claim that if humans evolved from monkeys they would have a much better
appreciation of the artistic value of monkey poop art. Meanwhile, the lab rats are
snickering behind the monkey’s backs saying that the monkeys are dumb and that
they have been stupid since ever since they were puppies. In the
of a Spider experiment, Reeko tackles the ins and outs of a theory proposed by some
scientists called the Theory of Evolution.
Police use many different scientific techniques to figure out who the bad guy is. They dust
for fingerprints, use special lights to look for blood, use chemicals to find out what
mysterious substances are, and sample DNA to figure out whodunit. And in addition to
figuring out who did it, they have to figure out how he did it. And to do that, they
often use a technique called blood spatter (not "splatter") analysis. Yep, in this
learn how blood spatter analysis works and what the different blood
patterns indicate about the crime. Don't worry, nobody dies but we have to admit
that it is pretty gross (but not as gross as when Mrs. Anderson sneezes and
plops out her glass eye).
Yeah, yeah, yeah, we know. You want to hang outside all day working on that tan.
Remember that while you're outside enjoying the Sun, Reeko is toiling away in the
lab making sure it's ready for your return to school. You can watch for new lab
construction projects including new science experiments,
more training of Ego the lab robot, and additions to the
science resources (science glossary,
lab news, and more crazy questions and
answers from the chess playing monkey. Have a great summer but please, don't
let your science skills go downhill.
Science can often times seem like magic. In this mind bending experiment,
we'll demonstrate a very basic scientific principle with an experiment that will
astonish your friends and confuse your Dad - and all you'll need is a PVC pipe,
Christmas tinsel, and a head of clean, dry hair to create a "magic wand" that will
float a colorful orb. It won't float your little sister or little brother out the
window but it's still pretty cool.
Reeko loves bubbles - all kinds of bubbles. Reeko loves chomping a big glob of bubblegum
and blowing bubbles the size of baseballs (and as a kid, used to giggle with glee
as his mother struggled to cut the gum from his hair). Reeko loves making them in
the bathtub using the "natural" bubble method (if you haven't mastered the natural
bubble method, eat beans, it helps). And of course, the science behind bubbles is
quite amazing too. In this
experiment, we'll create super strong bouncing bubbles.
As has been rumored for many years, there are secret areas of Reeko's Mad Scientist
Lab that few eyes have ever seen. Many have wondered what mysteries lie behind those
secret walls. Now it has been discovered that a top secret security card has been
lost somewhere in the lab. The person who finds and holds the top secret security
card will have complete access to all secret areas of Reeko's Mad Scientist lab.
Check the top, right-hand side of the site pages (under the Logoff button) for current
status and to see who, if anyone, is currently holding the security card. Note:
You must be registered and logged in to play. For further information, check
the Top Secret Security Card game
Be sure to register
as an official science lab member. Registered members will have access to
additional areas of the lab that non-registered members will never be allowed to
see and in fact, some lab games are only available to registered members. Registration
is easy, just

This just in.
Reeko has received word that a massive war between elephants and local dentists
is about to erupt. As you may know, elephants replace their teeth up to six times
during their lifetime making the “brushing your teeth” routine a non
event for them. Reports have been received of elephants making faces and shaking
their backsides while passing local dentist offices. You may also know that once
the elephant teeth are replaced six times, no new teeth grow in after that. As part
of the normal elephant life cycle, this means they cannot chew food and hence they
die a natural death from starvation. Reeko has received reports of dentists passing
by elephant graveyards and making “nah, nah, nah” sounds while sticking
out their tongues. For Pete’s sake, conduct this Elephant
Toothpaste science experiment and stop the madness before a full scale war
Reeko’s lab rats know that science is all about discovering new things. Now
at Reeko’s Mad Scientist Lab, you can check out Reeko’s latest news

Ever wonder why a really heavy boat floats while a small rock sinks like a... uhhh,
rock? Have you noticed that while in the pool, if you stretch out flat you will
float but if you curl up in a ball you will sink? Grab your lab coats and head for
the kitchen sink - our first science experiment
demonstrates those puzzling flotation principles.
How would you like to have your very
own hovercraft. You know - the futuristic vehicle that travels on air hovering inches
above the ground. Well grab your coats and head for the door. In this lab exercise
we're fixing to create a real, working hovercraft
... OK, so it's only big enough for a mouse but then again, you don't have a driver's
license so what'd you expect?
What if I were to tell you that I could make water flow uphill? No wait, don't
leave yet - this is serious. This lab experiment will show you that
what goes up doesn't always have to come back down.
A chemical reaction is a process where one type of substance is chemically converted
to another substance. That fizzling toilet bowl cleaner is a chemical reaction.
The fire in your fireplace is another type of chemical reaction. The smoke
that comes out of Dad's ears when you break one of his favorite golf clubs is a
result of a chemical reaction. OK, so maybe Reeko's stretching it a little with
that explanation. This science experiment
demonstrates a chemical reaction that's fairly common all around us (and we don't
have to go anywhere near Dad's golf clubs).
In this experiment, we’ll freak Dad out by lighting a five-dollar bill
and laughing madly as it burns. The flames will mysteriously extinguish and the
five-dollar bill will be left unharmed. Hmmmm… Is this science or magic?
Oh yeah, and we’ll tell you how to make $20 extra dollars in the deal too…
Here's a popular science experiment that's been
around for years and has left many kitchens in ruin (just kidding of course). In
the volcano experiment we build a real working volcano
that actually mimics the properties of the real thing.
Does you family head to the kitchen table every time they hear a fire siren? Do
you get even with the neighborhood bully by inviting him over to dinner? Does Dad
refer to the fire detector as the “oven timer”? It sounds like your
family might need cooking lessons. Well Reeko can’t (or won’t) provide
cooking lessons but he sure knows how to make
a cool little oven – out of a pizza box! And while we’re at
it we’ll learn how thermal collectors are able to collect sunlight and convert
the solar radiation into heat.
In this experiment we will learn about a little principle called momentum... Sometimes interesting
things happen when a totally motionless object gets in the way of a moving one.
To demonstrate - the next time dad finds out you've been in his toolbox again and
he's coming at you with that crazed look on his face, rather than running, flinching,
or ducking in terror, try freezing like a statue and see how it freaks him out.
Or better yet, try this science experiment
and see for yourself.
Did you work your way through all of the experiments? Did you find all of the hidden
tips and science facts? Take our Pop Quiz and
find out how 'science savvy' you are. And we promise, no matter how you score -
we won't send Mom or Dad a report card.
That wasn't enough cranial stimulation for one session? You need more experiments?!?!
OK... You asked for it - through this door you can enter
the top secret, select little scientists only section of Reeko's Mad Scientist Lab
What is quicksand anyway? How come I can see through glass? Do LifeSavers
really spark when you chew them? Chimp, the lab monkey, is back and available
to answer all those
weird science questions that have been driving us crazy...
Reeko has been receiving rave reviews on the new Pot
of Gold contest so he tore himself away from his latest genetic experimentation
and sprinkled more pots of gold around the lab! Join us on our search for the hidden
