How this 33/100 score is built

The score is computed from four CPSC-derived factors for chemistry sets or science kits - no opinion, no editorializing:

  • Injury volume162 ER visits/yr
  • Severity (hospitalization rate)2.1%
  • Fatality rate0.00%
  • 5-year trend+71%

What the CPSC Data Shows

Chemistry Sets Or Science Kits (CPSC product code 1393, in the Toys & Children's Recreation category) generate an estimated 162 emergency-room visits every year in the United States, adding up to roughly 3,241 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 33/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 71% over the last five years, with the busiest year on record being 2021 (451 estimated ER visits) and the quietest 2019 (70 estimated visits).

The single most common ER diagnosis for chemistry sets or science kits is poisoning to the all parts body, accounting for approximately 671 visits across the 20-year NEISS window, followed by laceration to the finger (435 cases). The 5-14 age group absorbs the largest share of injuries, about 1,552 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 2.1% of ER visits involving this product end in hospital admission or transfer.

Beyond the hospital-sampled NEISS projections, this page also aggregates 12 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how chemistry sets or science kits fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Consumer Incident Reports

Reports filed by consumers on SaferProducts.gov.

7/8/2012 · No Incident, No Injury · littlebits electronics · Arizona

The product "littleBits" is advertised as a children's toy. It contains small magnets along with other small electrical parts. It is sold on the Amazon website but it carries a warning which says: "Warning: Choking Hazard -- WARNING: Keep Away From All Children. Do not put in mouth or nose. This product contains small magnets. Swallowed magnets can stick together across intestines causing serious infections and death. Seek immediate medical attention if magnets are swallowed or inhaled." This product was discussed as a children's toy on CNN at 11:30 A.M. Arizona time on the show "The Next List" in an interview with the developer,[REDACTED]. As a pediatrician I state that this toy represents a very dangerous hazard to children and should not be promoted or advertised as a children's toy.

Chemical Burn With Children’s STEM Product

4/7/2015 · Incident, No Injury · C & A Scientific Co. · Illinois

The information below was taken from an email sent to the CPSC Information Center: The consumer believes that his alcohol burners present the same exact problem as the ones in Recall# 06-061. The consumer has 50 unsafe wick-less metal alcohol burners (used in scientific experiments). Description: The metal alcohol burner consists of a stainless steel tank with a screw-on steel lid. A copper tubing wick in the shape of a loop is soldered on the top of the burner's lid. The burner and lid measure 3-inches in diameter by 3 ½-inches high. The burner also has a separate metal top which fits over the copper wick to act as a snuffer, and a metal heat shield designed to sit on top of the lid. It has a rubber keeper to prevent vaporization of alcohol. The item number 97-5320 is printed on the burner's packaging. The possible name of the manufacture is “Premier” located in China (see photo of shipping container). The shipping container has this information on it also: C.A PO. No.P182 BALTIMOR C/NO. MADE IN CHINA. A possible injury or property damage can occur due to flammable alcohol leaking from the holes located in the copper tubing on the upper coil portion of the burner. The holes are in a placement where the rubber keeper/stopper cannot prevent fuel from leaking out when tipped over or when the internal temperature of the fuel tank rises and forces fuel to rise upward through the copper tubes leading to the coil on the surface of the burner. (See photo of hole not being covered by rubber keeper/stopper) I have inspected 10 out of the 50 received and all have the same hole placement. (see photo of hole in relation to rubber keeper/stopper). On or about March 21 is when I observed the alcohol leaking from the holes in the copper coil. At that time I notified the retailer of the problem. Their response was: “as to the product recall, we checked with the manufacturer and that was for a previous model, not this one”. Dated: March 23, 2015 On or about March

4/3/2019 · Injury, Seen by Medical Professional · MERCHSOURCE LLC · Virginia

There is a science toy with the Discovery Logo called Discovery Super Stink Lab. The kit is really dangerous (EMTs were called to our house), the stink permeates everything you own (which has to be thrown out if in contact), and the product needs to be taken off the market. There are tons of reviews on the internet about how terrible it is and I couldn’t agree more. My son was burned by the product and was screaming in the shower for 10 minutes from being in contact with the “toy”. I have bags of clothes and towels that have to be thrown out and our house reeks from the stuff. Just so you know the kit was used outside and only came in the house from getting on my son.

4/23/2014 · Injury, First Aid Received by Non-Medical Professional · Fascinations, Inc · Massachusetts

We bought my 7-year-old son the Fascination AntWorks ant farm for his birthday on April 1, 2007. We also ordered the two tubes of red ants sold alongside the item on Amazon.com. The ant farm looked secure but the ants were able to burrow out, which they did this past weekend. Perhaps there was a small invisible gap in the plastic housing that we didn't see; it almost looks as though the ants bit or tunneled their way out. In any case, they escaped and bit my son all over while he slept. He has about 15 or so bites all over his body, and they are very itchy and painful. There were ants all over the floor of his room. We have since thrown away the ant farm and put out ant traps. Terrible! I wouldn't wish this on another parent, ever.

2/9/2022 · Incident, No Injury · SCIENTIFICS DIRECT · Unspecified

1/25/2022: The consumer and her granddaughter were conducting an experiment with the science kit. They placed a substance that came in the kit, into a glass container, that the consumer owned. The substance was supposed to be heated in the microwave for 60 seconds. However, after heating it for 30 seconds, the consumer’s granddaughter told her that the product was catching fire. The consumer said no and turned the microwave off. A few seconds later, she restarted it and within a seconds, the glass and the contents inside it, exploded in the microwave. Damage was limited to the product inside, but there was none to the microwave itself. The consumer cleaned the glass up without injury. 1/2022: The consumer called the manufacturer and reported the problem to them. Their rep. offered to reimburse her the cost of the kit. The consumer asked to speak with someone in their Science Department, but the rep. said that the person (name unknown) was unavailable and would call her back. She never received a call back. She is not sure if or when they’ll send the reimbursement, but she’s more concerned with discussing the safety of the product with the appropriate person in the firm. There was a precaution “only use with adult supervision.” There were no other warnings on the product.
