Thirteen children were taken to hospital Friday after hydrochloric acid spilled over during a science experiment class at an elementary school in Fukuoka, southwestern Japan, the local education board said.
The 13 six-graders felt poorly, with some complaining of headaches or sore eyes, according to the education board and other authorities.
The accident took place around 11:20 a.m. at Nagazumi Elementary School in Fukuoka's Minami Ward when one of the pupils spilled around 3 milliliters of hydrochloric acid by mistake on a table from a test tube.
