Balloon cars are so much fun and a great party "build and race" activity! Recently (cool) progeny revealed this awesome tutorial for a matchstick box balloon car!
They have some great step by steps and a video!
I've also seen a LEGO version over at Marshall.edu
This is one of those impress your kids at the dinner table kind of activities. Ask them to balance 2 forks and a quarter on the edge of a cup and only the quarter can touch. It's pretty funny to watch them try and come up with something that works. Here's how to do it.
Start with a cup, 2 metal forks, and a quarter. If it's a paper cup or some other light material make sure it has some liquid to weigh it down. I think the boys put water in to see it splash out when the quarter or forks fell in.
You put the quarter in the middle of the fork teeth with the forks facing the same direction like this
Then you balance the forks on the quarter which is on the edge of the cup. You adjust the positioning of your forks until they balance. Our forks are pretty curvy so they needed some adjusting.
Tada!
activity, science, show and tell in activities, science, show & tell I'm guest posting today over at The Fort! Hop on over to see how to make a simple and fun paper helicopter of sorts!
craft, crafts, diy, inspiration, science in DIY, activities, crafts, science My 9 year old saw this expirement somewhere and has been wanting to try it out himself so this one was all him! You take a clean buffalo chicken wing bone and sumberge it in white vinegar in a glass jar with a lid and let it sit for 3 days. After the 3 days it's supposed to be very "rubbery"
It hasn't quite been 72 hours but this is what we found
The ends were very bendy but the middle was still pretty rigid. He thought the ends were impressive though! We'll test again tomorrow/the next day and report our findings here!
My boys thought this was the coolest thing. All for the Boys friend Nicola shared this on our Facebook wall but the boys have watched it a couple times I thought you might want to see it too!
2 Canadian teens built a weather balloon structure for around $400 complete with GPS. The little guy reached a height of 80,000 feet and while the GPS did stop working when it was 4 miles up it actually started working again and they were able to find it 75 miles from their original launch point. How cool is that?
activity, lego, science in activities, science This is a fun little water "magic" trick. All you need is water, a glass, and a hankerchief or other thin cloth/towel. We used a tea towel becuase it's what we found!
Place the hankerchief/cloth over the glass.
Push the cloth down into the glass a bit so that it makes a little "bowl"
Pour the water through the cloth until the glass is about 3/4 or so full.
Pull the cloth tight over the top
Pick up the glass while holding the cloth tight
Turn it over carefully and fairly quickly (both of my boys very much expected the water to fall back through)
But it didn't!
Obviously he was impressed :) If you tilt the glass to the side a bit or shake it around a bit of water may trickle out. Just make sure you have the cloth held tight! Surface tension is a pretty cool thing isn't it?!
activity, science in activities, science Science Sparks started up last year and has TONS of science fun. I know a lot of you (especially those with the older kids) love doing these science activities so I thought I'd make you aware of this fun site!
They recently shared a tutorial on how to make a catapult that's a bit different than others I've seen. I'm always up for a new catapult creation!
I want to try making this eerie sounds device too! Thanks for inspiring Science Sparks!
I am all for easy science experiments and this is now on our list.
All you need is a bar of Ivory soap and a microwave and this:
Turns into this:
I saw this super easy tutorial over at Toys in the Dryer so head over there for the how to. Basically you microwave soap - my kind of experiment!
