Bend the wire, drop it in hot water and watch!

Description

These 3" (~7.6 cm) samples of Nitinol memory wire can be wound around a pencil to form a coil. When immersed in hot water, the wire returns to its original shape. The wires can be "set" into other shapes, using a candle flame. These wires have a smaller diameter than our memory wire sold by the foot. (10 wires per package)

Austinite Strain Temperature, A_S = 54^oC
Austinite Peak Temperature, A_P = 69 to 70^oC
Austinate Final Temperature, A_F = 73 to 74^oC

Martensite Strain Temperature, M_S = 41^oC
Martensite Peak Temperature, M_P = 35 to 36^oC
Martensite Final Temperature, M_F = 27 to 28^oC

Fun alloy

Metallic bonding is discussed in the chapter on ionic bonding in the book I use. I give each student a piece of nitinol and let them play with its memory properties. I call it a Christmas present. Students are amazed and impressed. Well worth it.

Used this with a lego robotics team that was interested in shape memory alloy for their research project- this was the only place I could find an affordable sample to use with kids- they LOVED it! It is amazing to twist these wires up, drop them in hot water and watch them pop back into their normal shape! They were interested in shape memory alloy for engineering buildings to prevent earthquake damage.

Memory Wire or Wired for Memory

Jan 18, 2013

The Memory Wire Sample Packet is everything I expected. I watched a demonstration of memory metal with Jacques during a tour of the Venus Project and thought wow - imagine living in such a fine community. Where the creator cared about people and wanted to build the safest housing possible. In his 90s he was healthy and he bent a large piece of it into a coil - hit it with the heat and voila! Now, I can use this to show others how far technology has come. Thank you for letting me play as an adult when I use this wire in workshops to demonstrate how we bend ourselves around our new partner and how we can straighten-up too! Great product! Thanks! I love science mixed with electricity and magnetism in my relationships! I love your site. This is not the only product I have purchased to have fun with! I feel like a kid in here!

Memory Wire

These wires reshape nearly instantaneously. You might want to play with them first - if students tie the wires in tight knots, the wire can't unbend from that. Water doesn't have to be really hot.

Memory wire

I used this with the high school chemistry and elementary science classes as an example of a useful alloy comparing it's properties to Ni/Cr, Onion's alloy and brass. The kids were rivited!

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary

Middle School

High School

2-PS1-2

Students can analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.

2-PS1-4

Students can use the Nitinol Wire in an investigation to construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

5-PS1-3

Students can use Nitinol Wire to make observations and measurements to identify materials based on their properties.

MS-PS1-2

Students can analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

MS-PS1-4

Students can use Nitinol Wire to develop a model that predicts and describes changes in particle motion, temperature, and state of pure substance when thermal energy is added or removed.

MS-PS1-6

Students can use Nitinol Wire in the design of a project. Students can construct, test, and modify a device that either releases or absorbs thermal energy.

HS-PS1-5

Students can use observations made of the Nitinol Wire as evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which the reaction occurs.

HS-PS2-6

Students will observe and communicate scientific information about why the molecular-level structure is important in the functioning of a material.
