Photochemical reactions. Please help project due 9/14 Photochemical reactions. Please help project due 9/14 HI, I am doing the black to clear with photochemistry project, and the solution is not changing color under the light and I am looking for possible answers. I am using tap water instead of distilled water. I am trying to get the solution to change from the iodine color to clear under light and depending on the amount of time under light the more clear the solution will get. It has so… Read more

Bouncing balls Bouncing balls My son chose the “bouncing balls” experiment for science fair and is now commited to it. The problem is since it’s not a full outlines experiment we’re having a difficult time finding an actual experiment to do and exactly what our variables should be. Any thoughts? Or a direction in a better outlined experiment that could fit into this topic? Re: Bouncing balls Can you provide the link to the exact project you're looking at on our site? I'm guessing it's one… Read more

Science fair question: comparing activators Science fair question: comparing activators Hello, my daughter wants to see how using three different activators (borax, liquid starch, and contact lens solution) affect the viscosity of the slime. We used the sciencebuddies experiment with contact lens solution as a starting point. We may have an issue now because I was thing that the activator was the lone item changing each time, however now I see that contact lens solution also requires baking… Read more

Can I test density for magnetic slime? Need guidance with slime variation for son's science fair experiment Can I test density for magnetic slime? Need guidance with slime variation for son's science fair experiment My 7th grade son and I are looking to do the variation on the slime experiment using magnetic slime but instead of observing qualitative results (is it stick? slimy? etc?), we are wanting to test the density. Does that make sense or is it a smart thing to test? Also, how could… Read more

Question about Arduino Mass Driver Question about Arduino Mass Driver Daughter is working on this (https://www.sciencebuddies.org/science-fair-projects/project-ideas/Elec_p094/electricity-electronics/arduino-mass-driver#materials) as a science fair project. She has all of it built and we have done a lot of trouble shooting but can't get it to move the projectile pas the first coil. I added an led to the breadboard where the hall effect sensor is connected (5v power and sensor) and confirmed… Read more

Infinity mirrors Infinity mirrors Hello, Can the infinity mirror works with images inside the box instead of lights? How will the image be seen if no light is in the box? Thank you. Re: Infinity mirrors The infinity mirror requires lighting inside the box to work. However, you could try mounting a semitransparent image (like something drawn on a projector transparency sheet) inside the box along with the LEDs, and you might see reflections of the image.
