Balloon Powered Car\nThis one is simple to build and a lot of fun while playing.\n\nWhat You Will Need\n\nOne big sized balloon\nTwo long wooden skewers\n3 drinking straws with one having a bendy side\nA stiff cardboard sheet\nA nail and a hammer\nBottle caps\nMasking tape\nSmall rubber bands\nInstructions\n\nCut the cardboard sheet into the shape of a car as you would see it from the top. The skewers go where the wheel axles do, so ensure they stick out at least 1/4th of an inch from the sides to accommodate the wheels. Match the dimensions to get this form.\nCut two of the straws to make the car wheels\u2019 axles and stick them to the bottom of the cardboard cutout where the wheels go.\nUse a nail to poke holes in the bottle caps.\nPlace one skewer into each straw and then push the wheels into place at the end of the skewers. You can secure the wheels in place by using CA glue.\nSecure the mouth of the balloon into the short end of a straw using rubber bands and masking tape.\nStick the straw on the centreline of the cardboard car such that the balloon sits on the car.\nInflate the balloon from the open end of the straw and pinch the open end to hold it inflated. Set the car on the floor and release it to make it move.\n2. Stethoscope\nThis little invention is a must-try for all kids!\n\nWhat You Will Need\n\nTwo funnels\nA long cardboard tube/paper towel core/plastic tube that the funnels will fit into.\nBalloon\nDuct tape\nInstructions\n\nInsert the smaller end of one funnel into the cardboard tube/paper towel core/plastic tube and secure it with duct tape.\nInsert the smaller end of the second funnel into the opposite end of the cardboard tube/paper towel core/plastic tube.\nStretch the balloon over the mouth of on funnel. Ensure it is tight. Fix it in place with duct tape.\nThe rest of the stethoscope can be decorated with coloured paper.\nTo hear the heartbeat, place the balloon end of the stethoscope over someone\u2019s heart and place your ear on the other end.\n3. Clear Bottle Ocean\nThis is one of the most fun kindergarten invention ideas for kids.\n\nWhat You Will Need\n\nClear empty water bottle\nWater\nBlue food colouring\nFunnel\nBaby or mineral oil\nGlitter\nSeashells and some beach sand\nTiny plastic sea animals from a hobby shop\nInstructions\n\nStart by removing any labels on the water bottle and clean away any residual glue to make it look clear.\nUse the funnel to fill half the bottle with tap water.\nDrop a few drops of food colouring into the water through the funnel. Be careful not to add too much, or the water will turn dark blue. Add just enough and stir to give it the colour of the blue ocean.\nNow fill the rest of the bottle with mineral oil.\nDrop some ocean sand, seashells, and plastic underwater animals into the bottle.\nClose the cap tightly and shake it. Allow it to settle, and you have the ocean in your bottle!\n4. Water-Glass Xylophone\nThis one is a great invention for you and your kids to have endless fun times playing music. If your children are inclined towards music, this instrument can go into their band.\n\nWhat You Will Need\n\nSix to eight identical empty glass bottles\nWater\nFood colouring\nPlastic or metal spoons\nInstructions\n\nArrange the bottles in a line on the table and fill each bottle with increasing levels of water.\nAdd a different drop of food colouring into every bottle so they all look distinct.\nTap the mouth of the bottles with the spoon and listen to the ringing sound they make. If two bottles make the same sound, increase or decrease water in one.\nOnce you are done fine-tuning the bottles, play it like a xylophone with the other instruments!\nYou can also experiment with using bottles of different shapes, sizes, and spoons made out of wood for different sounds.\n5. Smartphone Projector\nThis is one of the coolest invention ideas for a school project that can also qualify for a science fair.\n\nWhat You Will Need\n\nCardboard box/shoebox or any narrow rectangular box.\nClear tape\nHobby store magnifying glass or camera lens\nScissors or hobby knife\nA smartphone\nInstructions\n\nCut out the flapping lid of the shoebox so the top side is always open, and you can slide the phone into the box.\nOn one end of the box, cut a circular hole slightly bigger than the diameter of the lens you have at hand.\nUse clear tape to secure the lens in place inside the hole.\nFrom the cardboard lid you cut out of the box, cut a small rectangular piece that can fit inside the box.\nMake three alternating folds in this piece such that it forms an \u2018M\u2019, and makes for a good base for your phone.\nPlace the base inside the cardboard box and mount the phone on top of it such that the display faces the lens directly.\nClose all the curtains and point the projector towards a blank wall and play a video on your phone.\nMove the phone closer or further away from the lens so that it forms a sharp projected image on the wall like a movie screen projector.\n6. Egg Drop Container\nThis one is a fairly advanced project for older children, the results of which are sure to surprise you as well!\n\nWhat You Will Need\n\nA small plastic jar to hold an egg and wade around it\nBubble wrap/cotton roll/styrofoam/soft foam\nA cardboard box big enough to accommodate the plastic jar\nTape\nScissors\n4 long rubber bands\nInstructions\n\nThe idea behind the project is to come up with a number of contraptions using available materials that can safely hold an egg inside the plastic jar while it is dropped from the balcony.\nTry a number of methods using bubble wrap and foam to cocoon the egg and secure it inside the plastic jar while you drop it from the balcony.\nFor a real challenge, get rid of all the thick Styrofoam or bubble wrap wading and try to suspend the egg jar inside the carton box.\nStart by packing the egg securely inside the plastic jar by using only the soft foam. Give it enough space to move around inside and avoid packing it tightly.\nTake the cardboard box and poke two holes on each side 3 inches away from each other.\nThread a long rubber band into each hole such that the free/loose end is inside the box. These ends will be used to suspend the jar with the egg. They will act as bungee cords.\nOnce the rubber bands are threaded through all the holes, wrap them around the jar with the egg. Ensure the jar remains suspended in the middle of the box.\nTake the contraption to your balcony and 3..2..1 drop!\nSuppose the egg survives, then well done! If not, try again.\n7. Castle Lantern\nThis is an invention that is sure to impress all your friends!\n\nWhat You Will Need\n\nCardboard sheet\nScissors, hobby knife\nPaper glue\nLED Votive\nButter paper\nColours\nInstructions\n\nDraw the castle on the cardboard sheet with all of its four sides and colour it in your desired colours.\nUse the hobby knife to cut out the windows and doors.\nDraw little windows on the butter paper and glue them on the inside of the places where the windows were cut out from.\nMake four creases where the whole sketch can be folded into a 3D model of a castle.\nFold the castle and glue the sides in place.\nPlace the LED votive inside and keep it on your table.\n8. Paper Roll Kaleidoscope\nKaleidoscopes are excellent to introduce kids to the world of optical wonders.\n\nWhat You Will Need\n\nCore from a toilet paper roll\nTape\nShiny paper sheets or reflective sheets like Mylar\nScissors and hobby knife\nWhite flat cardboard\nDecorative materials, buttons, sticker, etc\nFlexible straw\nInstructions\n\nTo figure out the dimensions of the solid triangle (prism) that goes into the toilet paper core, draw a circular outline of the core on a sheet of paper.\nUsing a ruler and pencil, draw a triangle of equal sides that fits perfectly inside the core.\nGlue the reflective papers to the while flat cardboard such that it forms a stiff mirror-like sheet.\nUsing the length of each side of the triangle as a measure, draw a rectangle on the reflective sheet such that the breadth of the rectangle is 3 times the length of the side of the triangle. The longer side of the rectangle should be as long as the length of the toilet paper core.\nDivide the breadth of the rectangle into 3 segments (equal to the side of the triangle) and mark it using two parallel lines.\nUsing the line as a crease, fold the mirror-like sheet into a prism such that the reflective surface is on the inside.\nPush the prism inside the toilet paper roll and cover one side with a reflective sheet held in place by tape.\nAdd the decorative materials inside and cover the open end with a transparent film.", "question_type": "good", "location_related": "no"}}]
