Surface tension can be affected by detergents and soap. You can measure surface tension by counting the amount of drops it can hold. Do detergents increase or decrease liquid surface tension?

Great job investigating how detergents affect surface tension. I like that you carefully measured the drops and kept a detailed lab journal to record your observations. Your careful work and organized notes show real scientific thinking
Nice research work!
Nice job!
