Recent studies on educational tools have resulted in breakthroughs in students' interest and motivation.The aim of this study is to demonstrate the use of a developed educational tool (called P.E.A.R.L.) that enhances students' chemistry literacy.The research was conducted at SPK SMAK PENABUR KELAPA GADING, involving a total of 31 participants.A simple methodology was employed, constituting a quantitative study with a pretest and post-test structure.The test assessed participants' chemistry literacy, specifically focusing on their comprehension of thermochemistry concepts.It comprised four questions, evaluating both theoretical and analytical knowledge, referencing an article on the Beirut port explosion.Non-parametric tests were used for data analysis, revealing a significant increase in the average achievement of the students.This suggests a notable improvement in students' chemistry literacy, with a Wilcoxon Rank Test p-value < 0.001 at α=0.05.The rank biserial correlation value of 0.807 indicated a positive correlation in the data, falling within the 'large' effect size.The steps to build the Piezo Electric Alcohol Rocket Launcher (P.E.A.R.L.) were
