#SAVE these fun and no-prep science experiments!! ⚗️ Ink propelled Leaf Boat 🔹Material: Pen ink, leaf, water 🔹Method: Add a drop of ink on a tip of a leaf and put on water. Leaf runs like a boat. 🔹Science: 🍃It is known as Marangoni effect. The ink has a lower surface tension and lowers the surface tension behind the boat, while the water in front still has a big surface tension. It “pulls” the boat forward. ⭐️Toothpick Star 🔹Material: wooden toothpick, water 🔹Method: Break toothpick carefully in half without separating and arrange as shown in video. Now add a few drops of water in centre and watch it to form a star. 🔹Science: ⭐️ As the wood absorbs the water, due to capillary action, the soaked fibers expand. So, as the toothpicks straighten and push against each other, the inside of the star opens up into the final star shape. 🪙 Dancing coins magnet 🧲 🔹Material: 🧲Magnet, Coins, Ruler or stick, Straw 🔹Method: Arrange Ruler on pillars of blocks and put magnets on it. Now add coins one by one. And blow air to the last coin with straw. It will start spinning. Then you can rotate all the coins by blowing at 1st coin. 🔹Science: The attractive forces on the lowest coin are very weak – it’s practically hanging in the air. This allows it to rotate rapidly, relatively unhindered by friction. This principle also applies in the case of the coin tower – the magnet on the ruler attracts the topmost coin, which attracts the next coin, and so on. 🧪 Turmeric pH indicator Experiment 🔹Material : Baking soda, turmeric, alcohol based Sanitizer 🔹Method: Mix 1 tsp baking soda with water to form a runny paste. Write on a thick paper with this mixture and let it dry fully. Mix Turmeric and 2-3 drops of sanitizer. Apply it on the paper you wrote on. Your msg will turn red in color. 🔹Science: Turmeric is an indicator. Indicators change color when they react with a base (baking soda) which results in your message turning a deep red color. ✍️ Type ‘MORE’ if you want more such experiments!! 👉🏼Follow @vnmomschool and @mombae.blogger for more !! 👉🏼#share with parents interested in science. #scienceexperimentsforkids #stemplayforkids #stemactivities #science 07/10/2023
