An interesting little craft, use wooden sticks to make a floating balloon toy. Drill holes in the stick to allow air to flow inside, so that when we blow air from one end, the ping pong ball at the other end will float in the air. The simple science behind this technique is air pressure, lead your children to do one together!~
This is how it works in the end, just blow hard.
Materials:
Round wooden sticks, 3mm wire (length ~5-10cm), table tennis balls, wood paint.
Tools:
Electric drill, drill bits (7mm, 3mm), wire cutters, screwdrivers, sanders, pliers, hand saws.
Cut a wooden stick about 15cm (the length depends on the length of your drill bit).
Use a 7mm drill bit to drill holes inThe maximum length of a drill bit can be drilled directly in the middle.
Mark the drilled ends on the stick. Mark the drill bit to the radius length of the stick and drill vertically where you just marked. To test it, blow from one side (this will also remove excess sawdust).
Cut a piece of wire and use vise to shape it into the shape as shown. Place the circle directly over the hole to mark where to drill.
Put the balloon up to see if it is the right size.
Okay, now you can drill a hole to secure the wire.
Install the wire as shown, with the ring just above the stick hole.
Remove the wire and polish it, using a sander to create a whistle like a mouthpiece.
Note: Always use toy wood paint! Paint the sticks and wire and let dry.
Place the balloon on the wire ring.
Now you can let your children hold it and complete it. It should be very helpful for exercising their lung capacity~
