NEWTON’S CRADLE 1142.5

An Exhibit mimicking the desktop pendulum we have all played with on someone’s desk top

only with SLEDGEHAMMERS!

 

end of page

let’s cut one in half to see how it is made....

after interviewing many sledgehammers we chose ROCKFORCE

Now which weight.

8 lb was too small, 16 lb was too heavy and 10lb was just right.

ROCKFORGE 10 lb. Sledgehammer with 34 in. Fiberglass Handle

Fiberglass

Plastic Impregnated in and around fiberglass handle and Head.

now we are sure the head will not fall off in time..

don’t believe kid can actually get shoulder in 3.9” space and reach down to hammers. (will test with real kids before permanently locating horizontals)

SECONDARY GRAPHIC PLACEMENT

Hammers are all assembled
Testing Limits
can reach hammers at present
end hammers can hang up. will modify end hammers to prevent
distance out is good
3.9” is fairly tall. may not need so much
what if we approached it from a higher perspective.
Lets: move the access slot higher narrow the access slot modify end hammers to prevent hanging work out some limit barrier so hammers can’t get hung up
we are making revisions based on testing. bearings being machined for limiters
New location of interactive will cause modifications to design
Nissi and Cadence came over to test our work
Their initial instinct was to operate from both sides
being a little girl she was timid

we feel the height is good. these little girls could work the hammers, but little boys will be stronger
REVISED DESIGN
REVIEW EACH ISSUE

SYMMETRY can use squres for signage
we need poly sheeting on both sides of hammers to prevent kids form pushing and pulling the hammers out of alightment
we’re adding hoops on top of last hammers to prevent hanging up
