The answer is simple, but frustratingly inconclusive. It depends. These are 'how to', 'show and teach' or process speeches with literally squillions of topic possibilities.
You could spend hours, or even days, considering this 'how to' speech idea against that one, or that one, or that one. However, you don't need to.
The easiest way is to use the guidelines below to help you pick a good demo speech idea relatively painlessly and quickly.

What makes a demonstration speech topic a good choice depends on 6 essential elements. You'll want to consider each of them carefully.
1. Your interests
Your choice of demonstrative speech topic needs to be something you are genuinely interested in, and know about or, want to know about.
Without enthusiasm or knowledge, it's incredibly hard to inspire and persuade others that they want to find out more about a subject. And that's your goal!
Ideally when you finish your speech, you'll find yourself on the receiving end of question after question from eager listeners.
2. Who the speech is for
You need to think about your audience before making your final choice.
What demonstration speech topics would truly interest them?
If you're considering a 'how to' topic you know they already know well, is there something new you could teach them about it?
What would be of value, and appropriate, for them to know?
3. The setting of the speech
Where is the speech to be given? In a classroom? In a public hall? In a living room? In the open air?
Does what you're planning to do fit the venue?
4. The time you've got to prepare the speech
Does the topic you're considering need a long time to prepare thoroughly? Are there visual aids you need to make to accompany it? How much research do you need to do before you can begin to prepare the speech?
5. The time you've got to give the speech
There is no point in choosing something complex with a large number of steps to show and teach if you don't have the time to cover them. What you select needs to fit easily into the allotted time limit.
If you really want to tackle a big topic, and it's a good fit with your audience, if it's possible, break it down into smaller, manageable pieces. Then choose one or two aspects (sub-topics) you know you can cover well in the time you have available.
For instance, how to knit has many elements: how to hold the needles, how to cast stitches on, how to choose the right wool, how to read a knitting pattern, how to do a specific stitch... Any one of those could become a speech.
6. The guidelines for assessment ...
... if the speech is part of a public speaking course.
You may find there are restrictions on using varying forms of visual aids: video or power-point presentations for example. Check before you make a final decision.
Use the 'how to' topics below to kick-start your own creativity. Think of them as beginnings or starting points.
Rather than pick the first idea that jumps out, build up a short list. Then go through it assessing the positive as well as negative aspects of each idea, keeping the audience members, your interest, setting, time and assessment needs in mind.
