    The “Storm in a Cup” looks really interesting, but the link seems to be broken or down. The site will not open for me.

    Can not view anything

    I was shocked to see a toddler so close to this experiment! 6% Hydrogen Peroxide is a strong oxidizing agent and body tissue irritant. I would consider this a form of child endangerment. This demonstration is meant for older students to study a chemical reaction, this is not “play foam”. It should only be used in safe environment with safety shield or safety goggles. Handler of hydrogen peroxide should be wearing plastic gloves.

    When I first saw the picture, I thought this looks like the Elephant toothpaste demonstration, but seeing the toddler, I immediately thought someone had found something else that had a similar reaction and I was curious. Being a science teacher, I would only do this experiment in a controlled setting. I have debated doing it with my 8th graders because they need to understand this is not like the hydrogen peroxide they are used to seeing. I agree with Jayne, the strength of the peroxide alone would have me wondering why someone would put a toddler around this reaction…..the first thing they want to do is touch. Save it for the lab!!!!

  5. Deborah Rol says:

    Mix corn starch and colored water in a flat plastic plate. The consistency should be similar to that of toothpaste. It will be hard to get it all mixed, but that is part of the fun! Pick it up in your hand and squeeze….it will feel hard and when you open your hand, it turns back to slime! Leave it in the plate and punch it with your hand… turns hard! Fun to play with and rinses off with water… outside as it might get messy….but fun!

    Jayne…..please don’t feel the need to lecture people. Who do you think you are? Doesn’t your 22 years as a teacher give you enough of an opportunity to control people? Each parent knows what their child’s limitations are, and can decide on their own how to supervise their children. People like you make me sick.

  7. Tina says:

    Liz Parker people like you make me sick. Two different people versed in the field of science have both stated that the experiment is dangerous to be done around young children. They are both concerned that people whom do not share their same background are uninformed of the potential hazard of allowing such a strong dilution of hydrogen peroxide near a young child. There are real dangers with doing this experiment that have not been cautioned. Yes a parent reserves the right to decide what they expose their child too- but they also deserve to be warned of the potential hazards of the experiments. A science teacher has stated her qualified opinion that certain safety precautions should be taken and her amazement that none were. It isn’t about knowing what your child can handle but what might actually cause them harm and YOU harm too by not knowing the chemical components in the experiment. You make me sick because you so simply dismiss years or practice and knowledge. It is people like you who endanger their children knowingly because you think you know better than a professional.

  8. Tina says:

    Also Liz Parker if you read in the comments below the experiment you see where one woman posted that even the lady at the beauty salon suggested gloves be used when working with the peroxide.

  9. Bonnie Nielsen says:

    I am thankful for the people who said this is a harmful combination, I personally wouldn’t know, and I was looking at doing this experiment in my childcare, and am so thankful for reading the safety comments, It really should hold warnings on the experiment, I will not do this,

  10. Annette says:

    First of all, thank you for commenting about the hazards and safety precautions for this experiment. What I would like to know is how to properly dispose of this experiment. Thank you!

  11. Pat says:

    And on top of all the safety concerns, the experiment doesn’t work. After spending $$$ on supplies, including the recommended developer, it was a big flop.

  12. icon package says:

    It is remarkable, rather valuable message

    P.S. Please review

    we used regular OTC peroxide and it worked fine! :) Not as big of foam but still the kiddos had fun!

  14. Adrienne says:

    Another interesting experiment (completely safe): soak a few eggs in white vinegar over 2-3 days (store in the fridge). The vinegar will dissolve the shell but the inner membrane will remain intact. The result is a shell-less egg. Kids can hold it and turn it to see the yolk float around inside. It’s pretty cool. You may need to rinse off the residue from the shell. The membrane beaks easily so handle with care.

  15. katie says:

    Thank you a million to the two scientific experts. I would have had no clue there would have been such differences in otc hydrogen peroxide & this stuff! My 3 year old has extremely sensative skin (as do I) and I can only imagine what this could have done to her curious fingers! Thanks so much for sharing your knowledge! Not all of us parents have degrees and expertise in these fields and I , for one , am grateful to those of you who don’t mind filling us in!!
