Yellow mafic lures are a type of fishing lure that is designed to attract fish by imitating the appearance and movement of small fish or insects in the water. Mafic lures are typically made from a mixture of metals, such as copper, brass, and zinc, which are known for their durability and ability to create realistic swimming actions. The color yellow is often used in mafic lures because it is highly visible in the water and can easily catch the attention of fish. Many fish species are naturally attracted to bright colors, as they can signify the presence of food or a potential mate. Yellow lures can be especially effective when fishing in murky or stained water, as they stand out against the dark background and can attract fish from a distance. Mafic lures are designed to mimic the movement of prey species, such as minnows or insects, in order to trick fish into biting.

Mafic lures are designed to mimic the movement of prey species, such as minnows or insects, in order to trick fish into biting. They typically have a weighted body and a lip or bill that causes the lure to dive and swim in a lifelike manner. Yellow mafic lures often have additional features, such as rattles or holographic patterns, to add further realism and attract attention.
Pull The Tablecloth
In this activity, students see a classic "magic trick" illustrating inertia.
Once they understand the science behind the magic, it will be harder to pull the rug out from under your students!
The glass of water has inertia — it will not move unless a big enough force acts on it.
The force in this activity pulling on the glass of water is the friction between the tablecloth and the glass. Since the tablecloth and glass are slippery, the friction is quite small — it's enough to pull the glass along slowly, but not enough to accelerate the glass quickly when you snap the cloth fast!
Objectives
- Describe a scenario that demonstrates the property of inertia.
Materials
- Per Demo or Group:
Table or smooth, level surface
Tablecloth, cloth (slippery works best, like silk or satin, and seams will need to be removed), OR paper towel with no seams along the edges
Glass of water (ensure that the outside of the cup is dry)
Key Questions
- Why does the glass move when the tablecloth is being pulled slowly?
- Why does the glass stay on the table when the tablecloth is pulled out quickly?
- What has greater inertia, a glass full of water or an empty one?
- Have you ever come inside after a snowy day and cleaned off your boots? Why does kicking your shoes against the wall help the snow come off?
What To Do
- Using a smooth table top, place the glass of water on top of the dry tablecloth or paper towel.
- Pulling slowly, move the cloth towards the edge of the table. The glass should follow.
- With a sudden jerk (don’t hesitate!) pull the cloth from under the glass. One technique is to bunch the cloth up and grab it as close to the table as possible, then yank down and out.The table top and the bottom of the glass need to be smooth and dry so that a minimum of friction exists when the cloth is pulled from under the glass. A silk or satin table cloth works best, and seams will need to be removed.
- If you’ve done the trick correctly, you should be able to pull the tablecloth out from under the glass of water with the glass still standing.
Note: Be sure to practice this before demonstrating it in front of a group, and have some towels ready for clean-up, just in case!
OPTIONAL: An easier demonstration uses wax paper and a karate chop motion to slide the paper out quickly.
Extensions
- Try the same demonstration with a variety of objects. Can you accomplish the same feat with a whole place setting?
- Which objects are easier or more difficult to use, and why?
- Can you accomplish the same feat with a whole place setting?
- Teacher Note: Playing Cards and Pennies (another activity in this package) is a way for students to try a similar trick without smashing crockery!

When fishing with yellow mafic lures, it is important to consider the target species and the conditions of the fishing environment. Different fish species may be more attracted to certain colors or patterns, so it can be helpful to research the preferences of the fish you are targeting. Additionally, factors such as water temperature, water clarity, and time of day can also influence the effectiveness of yellow mafic lures. In conclusion, yellow mafic lures are a popular choice for anglers looking to attract fish in a variety of fishing environments. Their bright color and realistic movements make them a versatile and effective tool for catching fish. By understanding the preferences of the target species and adapting to the fishing conditions, anglers can maximize their success when using yellow mafic lures..
