Polymer Project – Journal #3

Slime Tests:

Measurements:

60 mL of PVA

16 mL of Borax

Stir until the sides are sticky

MAKES RED SLIME

40 mL of PVA

8 mL of Borax

Stir until the sides are sticky

MAKES BLUE SLIME

Freeze slime -> still moldable!

BLUE SLIME – COLD

COLD TEST: 

Test coolness after being taken from the fridge.

Warmth – put on a warm shoulder to test how long that warmth is maintained and how coolness is transferred as well as how it feels.

The more slime we made, we found the longer we could freeze. But we also found that you can’t put the slime in the freezer, as it won’t be mouldable. But if put in the fridge, then the slime can still have the mouldable qualities we want, but also maintain a cold temperature.

Left: 20 mL of PVA

Right: 40 mL of PVA

BOUNCE TEST:

Test #1 – When dropped from 30 cm, before the slime was put in the fridge, the slime bounced 3.5cm.

Test #2 – When dropped from 30 cm, after being in the fridge for 5 minutes, it barely bounced.

SHAPE TEST:

Test #1 – With the right amount of borax, the slime would hold it’s place for quite a bit. But after a few minutes, it started to droop.

Test #2 – After taking it from the fridge, no matter how long we kept it out, it maintained it’s shape.

STICK TEST:

Test #1 – The slime was not sticky, and would break easily.

Test #2 – After putting it in the fridge, it would break even more, and no shapes could be made in either of these tests.

PROTOTYPE #1:

Slimy and the amount we made was too small, but it was malleable and soft.

PROTOTYPE #2:

We made more slime this time, and it was malleable and soft.

FINAL PROTOTYPE: 

The perfect fit for everything!
