Chemcraft was a significant player in the world of children's chemistry sets, particularly in the early-to-mid 20th century. The Porter Chemical Company, which produced Chemcraft sets, was one of the leading manufacturers of educational chemistry kits. These kits were designed to inspire young scientists and were widely available in stores like Woolworth’s.
Chemistry sets, including Chemcraft, gained popularity in the 1930s and 1940s, but their peak came in the 1950s. They were marketed as educational toys that could introduce children to the wonders of chemistry, often containing a variety of real chemicals, labware, and instructional guides. Chemcraft was among the brands that helped establish chemistry sets as a staple of childhood learning.
Early chemistry sets, including those from Chemcraft, often contained substances that would be considered hazardous today. Some even included radioactive materials, cyanide, and strong acids. Concerns over toxicity and safety led to stricter regulations. Hazardous chemicals were removed, making sets safer but less exciting. Chemistry sets became more about learning than experimentation.
Today’s kits focus on safe, fun, and educational experiments, using household ingredients instead of dangerous chemicals. Digital and interactive chemistry kits have emerged, blending technology with hands-on learning. Chemistry sets have come a long way – from dangerous experiments to safe, engaging learning tools.

Likely a little too stylish for the science fair. meh.
This is one way you can stretch 6 seconds of time lapse to fit the 1 minute presentation you have to give.
I do love the soundtrack - wet new age ambience.
This really gross but endlessly fascinating growth occurred in a supposedly clean petri dish which my boyfriend "sanitized" and put into storage for future use in cultivating yeast strands for his homebrewing adventures.
7/14/08 - Not sure why this picture is getting so many views lately but if it's because any of you are mold/yeast/fungus experts, if you could explain why the thing has structure that would be really cool.
Only took one shot with the viv when we went out rocketeering on Christmas Eve... but when you capture the moment so perfectly, why bother with another exposure?

Astronaut Edwin E. Aldrin Jr., lunar module pilot, prepares to deploy the Early Apollo Scientific Experiments Package (EASEP) during the Apollo 11 lunar surface extravehicular activity (EVA). Astronaut Neil A. Armstrong, commander, took this picture with a 70 mm lunar surface camera. During flight the EASEP was stowed in the Lunar Module’s scientific equipment bay at the left rear quadrant of the descent stage looking forward. Aldrin is removing the EASEP from its stowed position.
I had seen this done on Pinterest and had to try it myself with all of the cold weather we have been having. All you have to do is add some food color to water ballons, then hang them outside so they can freeze. The colors come out beautiful.

In the dedication to his son Johnnie, the author writes:
“Among the experiments contained in this book, many are simple pastimes meant for the recreation of young and old, assembled round the family table.
“Others, on the contrary, being of a really scientific character, are designed to introduce the reader to the study of Physics, that marvelous science to which we owe the discovery of the steam-engine, the telephone, the phonograph, and many other wonders – a science which, there can be little doubt, holds in reserve many other miracles for man.
“The whole of these experiments, whether simple or complex, may be performed without any special apparatus whatever, consequently without the least expense. Our improvised laboratory is composed, as you will perceive, of such articles as kitchen utensils, corks, matches, glasses, knives, forks, and plates – in fact, such things as every house, the humblest in the land, possesses.
“In dedicating this book to you, I trust it may prove a pleasant souvenir, in the days to come, of the happy moments we passed together in working these simple wonders, and in constructing the homely apparatus used in our Magical Experiments.” – Arthur Good (Tom Tit), Paris, 1st of January, 1890
The book contains 150 Magical Experiments.
This is my Lava Lamp that I made at home. In this Lava Lamp I was trying to compare how much bubbles will come out if the cap was on or off.

Take a medium-sized sewing-needle with a very sharp point. Take up a position about three feet away from a wooden wainscot or door, and, holding the needle between your finger and thumb, endeavor, strongly launching it, to throw it, point forward, into the wood. No matter what your skill and perseverance, you will not succeed.
Now pass through the eye of the needle a simple bit of thread, and you will be successful in the feat without the slightest difficulty. The little light "make-weight" that you have added to your impromptu javelin transforms it into a veritable arrow, and causes the point, given the impulsion, to strike the object aimed at and "to stick."
Audiences will be amazed in this event as they experience the effects of very hot and very cold temperatures and what affects they can create with our friend Eggbert and in a show-stopping exothermic reaction. Volunteers will get to see matter transform from one state to another by tasting a fizzing Mad Science “burp” potion, and taking a Mad Science bubble bath and shower. They will also be in a scary movie scene using dry ice special effects!

When the kids aren't getting outside enough, we find little adventures to go on or science experiments to try.
This one teaches how fine particles can be highly flammable . (In this case, a pile of ordinary kitchen flour that the kids are blowing air through.)
Do not try this at home.
Do you have a lot of broken, short crayons? Put them to good use by letting the kids create unique artwork through this CRAYON MELTING ART activity. It’s a fun and easy-to-do process art activity for kids and science experiment in one.
What is Process Art?
Process Art is open-ended art....
KIPP Delta students from Helena-West Helena visited Hendrix College, Friday, Sept. 18, 2015. The students heard from Present Bill Tsutsui and participated in science experiments lead by Hendrix science professors and monitored by Hendrix students.

Christina's program for the Tweens this week was Science Experiments. The kids got to try to create static electricity with by rubbing records on cloth and hair and trying to pick up tiny objects.

Two forks are stuck into a cork and the cork is placed on the brim of the neck of a bottle. The cork remains balanced on the brim even when the bottle is tipped and emptied of its contents.
