Science project, subject, dipstick, wireless touch. Passengers were inspired by physics-week strategy problems. Who needs artificial Visual equipments to measure without touching. The purpose of the study is to devise Visual equipments to measure without touching. 2. to strengthen the math and physics skills. Create Visual equipments, wireless touch the dipstick, then remove the knowledge of physics and mathematics used to calculate refractive index and the thickness of the glass and acrylic sheet. From the experiment. It found that the wireless device, touch the dipstick fabricated matmarot that measure the thickness and refractive index of glass and acrylic sheet and the value contains the value closer to measured values from woenia.
