ONE STEP CLOSER

Ok, I haven't decided what I want to do just yet, but I've set myself a deadline of tonight.
Tonight I shall have a SRP project.
I will do this! But I am one step closer, right now, to choosing an idea. It seems as if people like the idea "How caffeine affects the body - heart/pulse rate, breathing rate, body temperature, typing speed, typing accuracy, etc."
The few others that I have chosen to consider are:

• How and what materials are best to make a working telescope
• Whether the absence or presence of a net affects a free throw in basketball
• Whether watering a plant with water containing caffeine affects the plant, and whether watering a seed with caffeinated water affects germination
• How different erosional techniques affect different types of soil
• Whether storage temperature, area of storage, type of storage and time affect the pH level in different types of juice

So by tonight I WILL have the idea for my SRP. I'll be back :)
